FT Call for Proposals

Content owned by kchiboucas

Gemini North and South are accepting proposals for the Fast Turnaround (FT) program in this call. Here, we give information specific to this proposal cycle. Please see the other FT pages - particularly the rules - for general information about the program. FT (dual anonymous)-specific proposal templates (GemPhaseI_FT_dual) must now be used for all FT proposals. See the "PIT information" section below. The 2024A PIT must be used.

Important dates

  • Proposal deadline: 12:00pm (NOON), Hawaiian Standard Time (HST), April 30.

  • Please ensure the latest version of the PIT is used for submission (see the PIT information below).
  • Reviews must be completed by 23:59 HST, May 14. If you have submitted a proposal, but by the 2nd of the month have not received an email from FT regarding reviewing proposals, contact FT as soon as possible.
  • Results will be announced by May 21, 2024.
  • The deadline for preparing observations (Phase II) is May 30. Accepted programs meeting this deadline will be active from 1 June until 31 August 2024.
  • FT observations will be merged with the queue and observed on queue nights.

Dual Anonymous Review Process (DARP)

  • Since Feb 2021, we have been using a dual anonymous review process. New proposal templates for FT have been updated. DARP compliance is mandatory. Proposals using the wrong template will be removed from consideration.  Proposals that do not follow all the DARP guidelines will either be removed from consideration or sent to the directorate for review.  
  • Guideline for PIs
    • Enter information of the proposing team with the Phase I Tool (PIT) as usual.
    • Use the FT specific template.
    • The proposal template has been updated to be compliant with DARP since Feb 1, 2021
    • Avoid mentioning names and affiliations of the team in the PDF attachment that could be used to identify the proposing team.
    • Avoid claiming ownership of past work. (E.g., “my successful Gemini program in the previous semester (GS-18A-xxx)”, or “our analysis shown in Doe et al. 2020…”)
    • Including text in proposals discussing previous use of Gemini is ok, as long as that work is not referenced and program IDs are not listed.
    • Cite references in passive third person, e.g., “Analysis shown in Doe et al. 2020”, including references to data and software.
    • Do describe the proposed work, e.g., “We propose to do the following…”, or “We will measure the effects of …”
    • Unpublished work can be referred to as “obtained in private communication” or “from private consultation”.
  • Guideline for Reviewers
    • Accept the assigned proposals based on abstracts whether you can provide an unbiased review or not.
    • Review proposals solely based on the scientific merit of what is proposed.
    • Do not spend any time attempting to identify the PI or the team. Even if you think you know, you can be wrong.
    • Utilize neutral pronouns (they/the PI/the team) when you write comments.
    • Flag the proposals that have not been sufficiently anonymized but DO NOT penalize them by lowering grades. (The FT support team will check the flagged proposals and send any violations to the Gemini Directorate for review.)  
  • More detailed guidelines can be found on the FT webpage

Eligibility

  • PIs from all participant countries (except Chile) taking part in the FT program may apply for this cycle.
  • PIs from UH are able to apply for FT time at GS as US, but may not apply for GN time. 
  • Chile and UH have withdrawn from Fast Turnaround since 2021A and 2024A, respectively.
  • In agreement with Subaru Observatory, Japanese community proposers may only apply for up to 4 hrs of time on a single proposal (and no more than 4hrs total will be awarded to Japanese community PIs in a cycle).  
  • PIs from participant countries whose FT time for the semester has been used up should not apply for the remainder of the semester. At this time, KR has used its full allocation and KR users should not apply for the remainder of 24A. Note that some participant countries only have very small amounts of FT time available each semester. AR has only a total of 4h available for 24A.  See Rule #4 and Q&A for more information.

Acceptable RA ranges

  • Gemini North: Targets from about RA = 10.5 hr to 5 hr are acceptable during this cycle. Note, however, that RAs near 10.5h will only be accessible for a couple hours during the first half of the first month (June) and only at northern declinations (Dec > 0) . Likewise, RAs near 5h will only be accessible for a couple hours during the final month (August) and again only in the above declination range. Note Rule #9; an FT program may not fully backload its three-month active period; at least one of its targets must be observable during its first active month.
  • Gemini South: Targets from about RA = 10 hr to 4.5 hr are acceptable during this cycle. Note that RAs near 10h will only be accessible for a couple hours during the first half of the first month (June) and only at favorable declinations (Dec < 0) . Likewise, RAs near 4.5h will only be accessible for a couple hours during the final month (August) and again only in the above declination range. Note Rule #9; an FT program may not fully backload its three-month active period; at least one of its targets must be observable during its first active month.

Available instruments and observing modes

Gemini North

  • GMOS-N, GNIRS, and MAROON-X are available throughout much of the cycle.   
  • We are offering Altair in NGS mode only, with GNIRS.
  • The GNIRS Low-Resolution IFU is offered. Reduction of LR-IFU data is supported under the newest version of Gemini IRAF (v1.16) that can be found here.
  • There are no blocks currently scheduled for 'Alopeke during this cycle. However, if observations are needed outside of 'Alopeke blocks, please contact the FT team before proposal submission to check for additional availability.
  • Make sure to check the 24A schedule for detailed instrument availability.
  • For MAROON-X, it is now possible to check for target duplications.  Please see the instructions in the Phase I checklist.
  • Please contact the FT team in advance with any specific questions (Fast.Turnaround at gemini.edu).

  • As discussed in the rules and Q&A, please contact the Fast Turnaround team in advance of the deadline if you would like to propose for an unusual instrument configuration or observing mode.

Time available

  • At this point, only KR has used up their FT shares.  
  • Up to 17.7 (14.7) hrs per cycle at GN (GS) is available for FT observations. Very roughly, this implies:
    • 4 (3) hrs of 20%-ile conditions (IQ=20, for example; see this web page)
    • 9 (7.4) hrs of 50%-ile conditions
    • 12.4 (10.3) hrs of 70%-ile conditions
    • 15 (12.5) hrs of 85%-ile conditions
  • PIs may propose for up to the amount of time in their most restrictive observing conditions, subject to partner's time availability - see rule #4. For example, a proposal requesting CC50 IQ20 SB50 WVany conditions can request no more than 4 hrs of observing time.

PIT information

  • Proposals must be submitted using the version of the Phase I Tool specified on this web page
  • In the Time Requests tab, select "Fast Turnaround Observing at Gemini" as the proposal class and specify the reviewer (and mentor, if appropriate). Note that this is where the reviewer is defined; changes cannot be made after the proposal has been submitted.
  • For the pdf attachment to the proposal, the dedicated LaTeX/Word template specifically for FT proposals must be used.
  • Submitting the same proposal more than once during a given month (e.g. after correcting/editing a submitted version) should be avoided if at all possible. Only submit when you are sure your proposal is ready to be reviewed.

    • Utilize neutral pronouns (they/the PI/the team) when you write comments.
    • Flag the proposals that have not been sufficiently anonymized but DO NOT penalize them by lowering grades. (The FT support team will check the flagged proposals and send any violations to the Gemini Directorate for review.)  
  • More detailed guidelines can be found on the FT webpage

Eligibility

  • PIs from all participant countries (except Chile) taking part in the FT program may apply for this cycle.
  • PIs from UH are able to apply for FT time at GS as US, but may not apply for GN time. 
  • Chile and UH have withdrawn from Fast Turnaround since 2021A and 2024A, respectively.
  • In agreement with Subaru Observatory, Japanese community proposers may only apply for up to 4 hrs of time on a single proposal (and no more than 4hrs total will be awarded to Japanese community PIs in a cycle).  
  • PIs from participant countries whose FT time for the semester has been used up should not apply for the remainder of the semester. Note that some participant countries only have very small amounts of FT time available each semester. AR has only 2.2h and 1.8h available for this cycle at GN and GS, respectively.  See Rule #4 and Q&A for more information.

Acceptable RA ranges

  • Gemini North: Targets from about RA = 4.5 hr to 22.5 hr are acceptable during this cycle. Note, however, that RAs near 4.5h will only be accessible for a couple hours during the first half of the first month (March) and only at northern declinations (Dec > 0) . Likewise, RAs near 22.5h will only be accessible for a couple hours during the final month (May) and again only in the above declination range. Note Rule #9; an FT program may not fully backload its three-month active period; at least one of its targets must be observable during its first active month.
  • Gemini South: Targets from about RA = 4.5 hr to 23.5 hr are acceptable during this cycle. Note that RAs near 4.5h will only be accessible for a couple hours during the first half of the first month (Mar) and only at favorable declinations (Dec< 0) . Likewise, RAs near 23.5h will only be accessible for a couple hours during the final month (May) and again only in the above declination range. Note Rule #9; an FT program may not fully backload its three-month active period; at least one of its targets must be observable during its first active month.

Available instruments and observing modes

Gemini North

  • GMOS-N, GNIRS, and MAROON-X are available throughout much of the cycle.   
  • We are offering Altair in NGS mode only, with GNIRS.
  • The GNIRS Low-Resolution IFU is offered. However, be aware that the Gemini IRAF package for the LR-IFU is in preparation and will not be released until May 2024. In the interim, PIs who receive FT data may request a patch package, which is made available on a best-effort basis only; bugs will not be fixed before the May release.
  • LGS is not currently offered this cycle.  Please check back ahead of the deadline for any updates.
  • Alopeke is available during blocks in March and May. If observations are needed outside of these blocks, please contact the FT team before proposal submission to check for additional availability.
  • Make sure to check the 24A schedule for detailed instrument availability.
  • For MAROON-X, it is now possible to check for target duplications.  Please see the instructions in the Phase I checklist.
  • Please contact the FT team in advance with any specific questions (Fast.Turnaround at gemini.edu).

Gemini South

  • GMOS-S and F2 are available this cycle. Note that data reduction software for GMOS-S (with new CCDs) will likely not be available until mid-2024. 
  • F2 MOS is limited by the number of masks that can be inserted in the instrument and is not offered every FT cycle. It is offered in this cycle. Please read about its capabilities carefully. Since pre-images will be needed for most programs, F2 MOS targets are further restricted between RA 8 hr and 20 hr in this cycle.  Please contact the Fast Turnaround team before submission if you believe you will not need pre-imaging.  A maximum of 8 masks can be installed in the instrument.
  • IGRINS and Zorro are also available for some part of this cycle. Please check the instrument's schedule or contact the FT team in advance with any specific questions (Fast.Turnaround at gemini.edu).  If you require Zorro observations outside of the Zorro block, please check with the FT team ahead of proposal submission.
  • GHOST is not offered for this cycle.
  • Make sure to check the 24A instrument schedule for detailed instrument availability.
  • GeMS/GSAOI are not offered via FT.

Both telescopes

  • FT observations may not be executed during classical observing, or priority visitor (PV), depending on the prevailing conditions.

  • MOS observations are available for FT, subject to some caveats/restrictions.
  • As discussed in the rules and Q&A, please contact the Fast Turnaround team in advance of the deadline if you would like to propose for an unusual instrument configuration or observing mode.

Time available

  • At this point, no partners have used up their FT shares
  • Up to 17.7 (14.7) hrs per cycle at GN (GS) is available for FT observations. Very roughly, this implies:
    • 4 (3) hrs of 20%-ile conditions (IQ=20, for example; see this web page)
    • 9 (7.4) hrs of 50%-ile conditions
    • 12.4 (10.3) hrs of 70%-ile conditions
    • 15 (12.5) hrs of 85%-ile conditions
  • PIs may propose for up to the amount of time in their most restrictive observing conditions, subject to partner's time availability - see rule #4. For example, a proposal requesting CC50 IQ20 SB50 WVany conditions can request no more than 4 hrs of observing time.

Gemini South is accepting proposals this round for GHOST in Shared Risk mode through the Fast Turnaround (FT) program. We are not offering any other instruments in this FT round. Here, we give information specific to this FT proposal cycle. Please see the other FT pages - particularly the rules - for general information about the program. FT Dual anonymous-specific proposal templates (GemPhaseI_FT_dual) must now be used for all FT proposals. See the "PIT information" section below. The latest 2023B PIT must be used for this 23B special call.

Important dates

  • Proposal deadline: 12:00pm (NOON), Hawaiian Standard Time (HST), September 30.

  • Please ensure the correct version of the PIT is used for submission (see the PIT information below).  
  • Reviews must be completed by 23:59 HST, October 14. If you have submitted a proposal, but by the 2nd of the month have not received an email from FT regarding reviewing proposals, contact FT (Fast.Turnaround at gemini.edu) as soon as possible.
  • Results will be announced ~ November 1, 2023.
  • The deadline for preparing observations (Phase II) is November 15. 
  • Observations will be conducted during the GHOST Shared Risk run, which is planned for 30 November - 19 December 2023.

Dual Anonymous Review Process (DARP)

Since Feb 2021, we have been using a dual anonymous review process. New proposal templates for FT have been updated. DARP compliance is mandatory. Proposals using the wrong template will be removed from consideration.  Proposals that do not follow all the DARP guidelines will either be removed from consideration or sent to the directorate for review.  

Guideline for PIs

  • Enter information of the proposing team with the Phase I Tool (PIT) as usual.
  • Use the FT specific template.
  • The proposal template has been updated to be compliant with DARP since Feb 1, 2021
  • Avoid mentioning names and affiliations of the team in the PDF attachment that could be used to identify the proposing team.
  • Avoid claiming ownership of past work. (E.g., “my successful Gemini program in the previous semester (GS-18A-xxx)”, or “our analysis shown in Doe et al. 2020…”)
  • Including text in proposals discussing previous use of Gemini is ok, as long as that work is not referenced and program IDs are not listed.
  • Cite references in passive third person, e.g., “Analysis shown in Doe et al. 2020”, including references to data and software.
  • Do describe the proposed work, e.g., “We propose to do the following…”, or “We will measure the effects of …”
  • Unpublished work can be referred to as “obtained in private communication” or “from private consultation”.

Guideline for Reviewers

  • Accept the assigned proposals based on abstracts whether you can provide an unbiased review or not.
  • Review proposals solely based on the scientific merit of what is proposed.
  • Do not spend any time attempting to identify the PI or the team. Even if you think you know, you can be wrong.
  • Utilize neutral pronouns (they/the PI/the team) when you write comments.
  • Flag the proposals that have not been sufficiently anonymized but DO NOT penalize them by lowering grades. (The FT support team will check the flagged proposals and send any violations to the Gemini Directorate for review.)  

More detailed guidelines can be found on the FT webpage
