Special Instructions 2006A
Instructions for Completion of Phase II/OT Science Programs: Semester 2006A
This page provides instructions for completing Phase II Science Programs for all Gemini North and Gemini South instruments. It includes submission details and procedural changes. Please read this page carefully!
Note: As in the previous semester the Phase II deadlines are hard deadlines for queue programs (see details below). Programs that have not completed their Phase II definitions by the deadlines will be dropped from the queue.
Distribution of Phase II Skeletons
All observations must be defined using the Observing Tool (OT) software. Gemini staff have translated approved Phase I proposals into the Phase II format for loading into the OT. In this process, the observations and other details entered in Phase I are used to construct a ("skeleton") framework of your Science Program.
Instructions on skeleton retrieval were sent to PIs on December 14. As in previous semesters, the Phase II skeletons are downloaded/uploaded directly from/to the Gemini telescope databases to enable more efficient and rapid processing. See more information on using the Observing Database.
A new release of the OT ("pulga") is available to support Semester 2006A Phase II preparation (as well as on-going 2005A and 2005B programs); do not use the previous "palote" public release. There are OT installation instructions available. If you are unfamiliar with the OT, there is an OT tutorial that provides a useful introduction. In addition, each instrument also has several web pages that provide guidance on observing strategies and how to describe these in the OT.
Relaxation of Observing Condition Constraints and Other Observation Changes
For semester 2006A the queue was constructed by filling the expected observing conditions (and overfilling the poorer than average conditions) but limited to the total available queue time (i.e. the total science time less scheduled classical nights and estimated Band 1 rollover programs). Band 3 programs, which now occupy the lowest half of the queue, are unlikely to be executed, and very unlikely to be completed, if they request conditions that are better than average (especially in cloud cover and image quality).
As in the previous semester we encourage PIs of Band 3 programs, in particular, to think carefully about relaxing the observation constraints within the context of their overall time allocation and approved science goals (e.g. by observing fewer targets). One useful analogy is to consider "how would I attempt this program if it were classically scheduled and the conditions were sub-optimal?".
If during detailed definition you find that the approved observations need to be modified, please follow the change request procedure.
The National Gemini Offices are responsible for Phase II support for the "established" facility and visiting instruments as mandated by the Gemini Board. Phase II support for the other instruments remains with the Gemini Observatory staff. In outline, the Phase II process for the established instruments is as follows:
- PIs interact with NGO support staff to complete Phase II using the OT for all observations with NIRI, including Altair, Phoenix, both GMOSs (including MOS mask design), T-ReCS, GNIRS and Michelle.
- All Phase II Science Programs are checked by NGO staff prior to being forwarded to the Gemini Contact Scientist. (Note that Gemini CSs will return any Phase II programs that are received directly from PIs, with instructions to contact their NGO).
- Gemini Contact Scientist checks Phase II Science Programs; if there is any problem the Science Program will be returned to the NGO support staff. The NGO staff will then iterate further with the PI.
- Only when the Gemini Contact Scientist agrees that the Science Program is ready will it be activated in the queue for execution. The PI will be notified that their program is in the active queue and that the Gemini CS is now the primary contact point.
If you wish to change the primary contact for this program, e.g. to a co-I, please e-mail both Sybil Adams (sadamsgemini.edu) and Simon Chan (schangemini.edu) with a copy to both Gemini Heads of Science Operations (ijorgensengemini.edu, mwestgemini.edu) and a copy to your National Gemini office.
To help us in tracking and resolving user problems, questions and suggestions, and thereby improving the software and web pages, please use the Gemini HelpDesk. This allows us to ensure that no queries are missed and help us improve the software and documentation. A streamlined interface is available for Phase II queries, keyed to your Gemini Program ID (e.g. GS-2006A-Q-12). As with the regular HelpDesk interface, your query will be directed to the specific NGO or Gemini support staff. Support assignments do change occasionally and you can verify the contact names from the "interactive snapshot" of the Observing Database, accessed from the contents list on the schedules web page. (The NGO and Gemini support staff email addresses are listed on the support staff web page).
The mechanism for submitting your completed Phase II Science Program is similar to skeleton retrieval (see the Observing Database information for more details) and is the same for all instruments (although submission of MOS mask definition files, and finding charts, is currently handled separately, outside of the Observing Tool, via direct email to your Gemini Contact Scientist).
Dates for submission of completed Phase II information are (all 6pm local time):
|Phase II deadlines for all instruments|
|12 January||Early submission, recommended for any programs and especially advantageous for observations that can be executed early in the semester|
|10 February||Mandatory deadline for all queue programs|
|various||Deadlines for GMOS mask design and MOS updates (several dates, synchronized with lunar phase)|
These deadlines apply to all queue programs including templates for Quick Response / ToO observations. (In addition there are periodic deadlines during the semester for GMOS mask design and corresponding MOS observation updates only).
PIs of all classical programs must also submit Phase II observation definitions. The deadline for these is three weeks prior to the first scheduled night. (See the 2006A classical schedule and 2006A semester/instrument schedule).
Programs that have not completed their Phase II definitions by the deadlines noted above will be dropped from the queue or schedule. In exceptional cases an exemption may be requested by emailing both Heads of Science Operations (ijorgensengemini.edu and mwestgemini.edu)
In some cases GMOS PIs may be contacted directly and asked to submit their Phase II early to provide sufficient observations for pre-imaging and MOS spectroscopy at the very start of the semester. All MOS pre-imaging observation descriptions must be submitted by the regular deadlines (see table above).
OT and Other Late-Breaking Changes for 2006A
The principal changes to the OT software are listed on the OT Release Notes page. There are also several new policy changes. Here we summarise how they affect Phase II observation definition and point the user to further details.
Notification of Data Taken and Electronic Distribution
The "Notify PI" checkbox in the OT observation component is not yet active. Nonetheless, raw data are available "immediately" (usually within minutes) from the Gemini Science Archive using your OT (observing database) key for secure access to proprietary data. PIs will be notified by email once their data have been quality assessed and ingested into the archive and are available as a package along with other metadata (observing logs, calibrations etc). See more information about data retrieval from GSA.
GMOS nod-and-shuffle darks
Any dark frames for nod-and-shuffle modes must be defined explicitly by the PI. The GMOS Baseline Calibrations page describes the calibrations that will be taken for each observation or program and which need to be specified by the PI.
Altair Field Lens
A field lens in Altair dramatically increases the isoplanatic angle, giving improved Strehl and sharper images at larger distances from the guide star, subject to atmospheric conditions (i.e. the height of the dominant turbulence). PIs must specify use of the field lens using the OT Altair component. More information can be found on the Altair field lens page.
Status of Submitted Programs and Observations
The 2006A queue summary and "interactive database snapshot" pages show the current execution status of all queue programs and indicates when data have been taken. (For the next level of detail, click on the "execution status" link under each program to see the status of each observation or on the execution log links in the contents list to see which observations were executed each night).
