Subaru/Gemini Time Exchange Program
This is the instruction for Subaru users who intend to apply for Gemini
telescope time through the Subaru/Gemini Time Exchange Program in S19A/2019A.
Directors of Subaru Telescope and Gemini Observatory agreed to continue a time exchange program for the semester which corresponds to 'S19A' of Subaru and '2019A' of Gemini, both begin on 2019 February 1 and end on 2019 July 31. This time exchange program is coordinated so that astronomers in each community can mutually access unique instruments of each telescope.
In S19A, normal observations with Gemini telescope, except ToO observations, will be executed in a 'classical' or 'queue' mode whichever you prefer. Proposals requesting Target of Opportunity (ToO) observations can be submitted to Gemini, where accepted ToO programs will be executed in a queue mode.
Scientific merits of the proposals are reviewed and determined in each TAC independently (namely, proposals from the Subaru community using Gemini are reviewed by Subaru TAC). Those who have direct access to Gemini time must refrain from submitting proposals to this program.
1.1 Gemini Large and Long Program (LLP)
The Subaru community can apply for the Gemini Large and Long Program (LLP), through the Subaru-Gemini time exchange program. But the application for Gemini LLPs is available only in the call for proposals for B semesters, unavailable in S19A.
1.2 Fast Turnaround Program
The Subaru community can apply for Fast Turnaround programs, in which up to 5 nights per semester are available for Subaru Community. Their submission deadlines are independent from the deadline of the S19A Call for Proposals The review of Fast Turnaround programs is made following the rule set by Gemini and is done independently from Subaru TAC.
2. Available Instruments and Observing Time
Gemini instruments available to the Subaru community in S19A are as follows:
GMOS (North or South)
GSAOI+GeMS (South): Queue only, Bands 1 & 2 (IQ70&IQ85)[more than two runs are expected for operation]
Please check the Gemini 2019A Call for Proposals, which will be released 2018 Augus 31 (HST).
For Altair , AO with natural guide stars (NGS) are available with combination of NIFS, NIRI, and
GNIRS. GN Laser Guide star system will not be offered in 19A.
The unique capabilities of available Gemini instruments, compared to the existing Subaru instruments, are briefly summarized below for the Subaru community.
Note that the above summary is not comprehensive. Please refer to the Gemini webpage for the details of the instruments and telescopes.
We anticipate that the amount of the exchange time available in S19A is minimum 5 nights, but the actual number of exchange nights is dependent on the oversubscription rate of both telescopes and scientific evaluation by each TAC. The minimum amount of requested nights for each classical program is 1 night. However, for queue observations, programs which require repeated observations of short exposures are welcome.
All Gemini facility instruments listed above are available for ToO programs. There are two types of ToO observations. Rapid ToOs require observations within 24 hours, while Standard ToOs will have a slower response time of more than 24 hours. The PI must specify whether the observations require Rapid or Standard response. Rapid ToO programs will be charged for time spent on any observation that the Rapid ToO interrupts; both Rapid and Standard ToO programs will be charged for all on-sky calibrations.
Since individual instruments may have additional RA limits imposed, it is important to check the Gemini 2019A Call for Proposals, which will be released on 2018 Augus 31 (HST).
3. Proposal Preparation for Programs using Gemini Telescopes
3-1. Step 1. Phase-I Submission to Subaru ProMS
Proposers intending to apply Gemini observations via this Subaru Call for Proposals should access the ProMS 2.0 page to fill the webform. Proposals from the Subaru community to use Gemini are treated as ones of the Subaru Open Use Programs and are reviewed in the same way as other Subaru proposals.
How to complete the Application Form:
Please follow the instructions detailed in 'How to Submit'.
3-2. Step 2. Phase-I Submission to Gemini
All the proposals requesting Gemini time should also be submitted to Gemini's Phase I Application, by the deadline for Gemini's semester 2019A Call for Proposals (September 30, 2018 at 23:59 HST). Gemini will be updating the Phase-I Tool every semester, so please be sure to download the latest version from the website. With the new Tool, the science and technical cases, with Figures, Tables and References, are attached as a single PDF file. Latex and Word templates are available for download from the Gemini page, which explain the required contents and page limits.
We understand that such double submissions are inconvenient, but it is needed to match the current proposal processing systems of Subaru and Gemini. Your description in the technical justification section in the Gemini Phase-I form will be used for technical evaluation by Gemini. Regarding the scientific justification (SJ) section, you can just give the same SJ (of 2 pages; i.e., you do not have to reduce it) as submitted to Subaru TAC, despite that the prescribed SJ length in Gemini Phase-I form is only 1 page. SJ is used by Gemini staff for the purpose of understanding the science goal in order to provide adequate support. The target names cannot be concealed in Gemini Phase-I submission.
Please read the instruction in Gemini 2019A Call for Proposals carefully, when available (on 2018 August 31 HST). Subaru users should use Gemini PIT and submit their proposal by the deadline 2018 September 30 (HST). Please select "Subaru" for the "partner" in PIT submission tab page.
3-3. Step 3. Phase-II Submission to Gemini
The PIs of the accepted programs have to complete the Phase-II proposal submission to Gemini by themselves, following the instruction in the web page, Phase-II Overview.
