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!
The Phase II deadline of July 16, 2012 is a hard deadline for both queue and classical programs. Note that failure to submit a defined program by the Phase II deadline will result in the progam being canceled. Extensions are granted only in exceptional circumstances and only if requested prior to the deadline.
The mechanism for submitting your completed Phase II Science Program is by using the Store command in the Observing Tool and is the same for all instruments. See the Observing Database information for more details.
|Phase II deadlines for all instruments|
|16 July 2012||Mandatory deadline for all queue and classical programs.|
|MOS Mask Cut Deadlines||
MOS Masks are nominally cut at Gemini South for both telescopes. Please allow an extra 10 days for delivery to Gemini North. There are no plans to resume regular mask cutting at Gemini North.
The mask design and corresponding Phase II updates are submitted via the OT and then checked by the NGO contact before being forwarded to the observatory. Mask designs are checked internally by Gemini staff for technical feasibility at least once per week before being forwarded to the Gemini South mask cutting queue. The time between NGO mask design approval and mask availability for the telescope queue is normally less than 2 weeks for Gemini South and 3.5 weeks for Gemini North (due to mask shipping time). We strongly encourage all MOS PIs to submit their mask designs as early as possible (either at the start of the semester if not using GMOS pre-imaging or immediately after the pre-imaging is taken) in order to increase the chance that the MOS observations will be completed. Gemini reserves the right to not cut masks for queue programs submitted within 6 weeks of the end of the semester if the queue coordinators determine that the MOS observations cannot be scheduled.
Be sure to use the latest version of the mask design software.
Classical program PIs must ensure their mask designs have been submitted and cleared the NGO checks at least two weeks prior to their arrival at Gemini South and 3.5 weeks prior to their arrival at Gemini North.
Note that all MOS observations must be defined by the phase II deadline. Observations without masks will be reviewed and set to "On Hold" until the masks become available, at which time the PI will have a chance to make modifications if necessary.
25 July 2012
|Dates of preparation of Gemini-North LGS targets lists by Gemini staff for approval by Space Command. Change requests for target additions and alterations must be made well in advance of these dates for the target to be included in the next LGS run, and observations set to "ready" at least two days prior. (These restrictions do not apply to LGS programs granted ToO status.)|
The mandatory deadline applies to all queue and classical programs including templates for Quick Response / ToO observations. The mask design deadlines are more flexible but we encourage PIs to submit their mask designs and final MOS observations as early as possible (see the table above). The LGS target list preparation dates are subject to change if LGS runs are rescheduled.
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. In all cases it benefits programs with early targets to get their Phase II ready early, as some 2012B programs will most likely be observed at the end of 2012A to help fill 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 of the OT. In this process, the observations and other details entered in Phase I are used to construct template observations, including standard and calibration observations. NGO staff may have made some adjustments based on the OT example libraries. Please use any templates as the starting point for completing the Phase II observations.
Instructions on skeleton retrieval were sent to PIs on June 18, 2012. 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 is available to support Semester 2012B Phase II preparation (as well as on-going 2011A, , 2011B and 2012A programs); do not use the previous "2012A" 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. OT libraries with example observations and configurations for each instrument should be fetched and used in conjunction with the included template observations.
OT and Other Late-Breaking Changes for 2012B
The principal changes to the OT software are listed on the OT Release Notes page. There are also several new policy changes. Here we summarize how they affect Phase II observation definition and point the user to further details.
OT Templates and Libraries
Template observations based on the example OT libraries are now created automatically. The OT libraries contain additional information including examples of different types of observations and some standard star information. We recommend that you fetch the OT libraries and use them in conjunction with the template observations. Fetch the latest libraries by selecting "Fetch Libraries..." from the File menu of the OT Science Program Editor.
NGO staff may have made some changes to selected programs in order to improve the Phase II process.
Please use these templates as the starting point for the final Phase II observation definitions. Contact your NGO contact scientist if you have any questions.
Many instrument libraries now include "Standardized Notes" which should be used if possible to efficiently convey important information to the nighttime observers.
Major new OT capabilities and procedure changes
- Inclusion of new Template Observations
- Templates are filled in with the instrument resources selected in the Phase I proposal
- Acquisition and baseline calibration observation examples are included
- Templates are 'Applied' to targets and conditions to create draft observations for execution
- Template "group" can be spiit so that different templates can be applied to different targets
- Changes to templates can be 'Reapplied' to existing observations as a way to easily make changes to many observations at once.
- Templates can be regenerated from the template server to get the latest templates or start from scratch
- Automatic guide star selection for all instruments and wavefront sensors
GMOS-N CCDs should be E2V
All GMOS-N observations must use the E2V CCDs and 6 amp mode. See the GMOS Status page for news on the GMOS-North detector upgrade. Characterization of these CCDs is ongoing; only a new 6-amp mode has been commissioned for science use and there are no plans to commission the 3-amp mode. Please see the GMOS data format page for details on the 6 amp format. Releases are planned for handling data reduction with these new CCDs. Please download the latest release when it becomes available.
Relaxation of Observing Condition Constraints and Other Observation Changes
By default observations must use the observing conditions constraints approved by the ITAC during the Phase I process. Band 3 programs must use the approved Band 3 conditions. It is always acceptable to relax the conditions since more relaxed conditions lead to a higher probability of execution.
To change to better observing conditions than approved by the ITAC, or to add airmass or hour angle constraints, requires approval via the change request procedure. Target changes and other significant modifications to the original proposed observations also require approval, see the change request procedure for more information.
The National Gemini Offices are responsible for Phase II support for the established facility and visiting instruments. In outline, the Phase II process is as follows:
- PIs develop their Phase II using the OT template examples and interacting with NGO support staff as needed for assistance;
- Phase II Science Programs are checked by NGO staff who iterate with PI if needed, before setting observations to "For Activation";
- Once set for activation, the Gemini Contact Scientist will perform a final check before setting observations "Ready" to observe. If there is any problem the observation status will be returned to "For Review" for further iteration between the NGO and the PI.
- As observation status changes in the OT, the PI, NGO contact and Gemini contact receive emails. The PI must always fetch the program to ensure he/she has the latest version before making changes and storing again.
Status of Submitted Programs and Observations
The 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).
