Phase 2

Imporant Notices

1. The total time allocated by TAC includes overheads.
2. Seeing and transparency conditions must be chosen from the dropdown list in the Phase 2 sheet.
3. The maximum number of the short exposures (60 sec or shoter) is limited to 5 within an OB (the minimum Observation Unit), while the length of on-source exposure time of an OB must be equal to or shorter than 30 minutes (1,800 seconds).
4. Phase2 of Grade C and F proposals will not receive detailed feedback. Submitted version will be accepted as is. If there are any obvious errors, we may correct them without contacting PIs.

In Phase 2, for the accepted proposals, Subaru Telescope will ask PIs to prepare and submit Observing Blocks (OBs).

1. Please contact if you have any questions.
2. An OB is the minimum observation unit. The maximum length of on-source exposure time in an OB is 30 minutes (1,800 seconds). We recommend keeping the length of each OB short, as a shorter OB has higher probability of being executed than a longer one. However, note we are limiting the number of short exposures (60 sec or shorter) to 5 within an OB.
3. Subaru Telescope provides a Phase 2 tool. The spreadsheet allows the use of custom standard stars. Consult the Queue Mode Program PI Document for more details.
4. Check OBs with the Web check tool. If there are no errors, submit the Google Sheet through the Web check tool.
5. Subaru Telescope will review submitted OBs. We may ask PIs to relax observing constraints in order to increase the probability of OBs being executed. If it is possible to loosen the constraints, PIs will be asked to revise and re-submit Phase 2 sheets.

Phase 2 spreadsheets

• OBs are to be prepared with a web browser, editing a Google Sheets template which will be made available to PIs. Please contact us if access to Google Sheets is restricted. Phase 2 form in Microsoft Excel spreadsheet format can be provided.

Web check tool

Subaru Queue Google Sheets Checker/Submitter/Listing

• OBs (Phase 2 spreadsheets) can be checked with this 'Subaru Queue File Checker'
  1. Input your proposal ID, which is identical to the Phase 2 spreadsheets name (e.g., S24A-XXXQN).
  2. Press the 'Check' button.
  3. The check result, including errors if any, will be displayed.
• Submission of Phase 2 spreadsheets
  1. Input your proposal ID, which is identical to the Phase 2 spreadsheets name (e.g., S24A-XXXQN).
  2. Input your ProMS or STARS username and password.
  3. Press the 'Submit' button.
• Listing your submission history
  1. Input your propsal ID (e.g., S24A-XXXQN).
  2. Press 'List submissions' button.

Important Policies for Phase 2

1. Total on-source exposure time must equal to or be shorter than 30 minutes (1,800 seconds).
2. Seeing must be selected from 0.8, 1.0, 1.3, 1.6, or 100 arcsec (i.e., no constraints). Analogously, for transparency please choose from 0.7, 0.4, 0.1, or 0, the last value corresponds to "no constraints". Regarding transparency, note that we define it as the total throughput including the telescope and instrument, and not just the atmosphere. Numbers will be rounded to the first decimal place. For example, seeing (transparency) 0.84 arcsec (0.65) for an OB requesting 0.8 arcsec (0.7) will be considered 'good'.
3. Observing constraints for any OB must not be better (stricter) than the ones given in the original proposal (Phase 1).
4. All targets must be listed in the original proposal. Neither change nor addition of targets is allowed in Phase 2. Consult the Queue Mode Program PI Document for tips on the correct format for the associated target codes and coordinates.
5. Each OB code must be unique. OB codes cannot be changed once a semester starts, even if PIs are asked to relax constraints.
6. Total required time (exposures plus overheads) may exceed time allocated by the TAC; however, as soon as the allocated time is all used up, the program is considered 'complete'.
7. We will not accept Phase 2 submission after the deadline without an agreement between PI and QWG. If you are willing to proceed to Phase 2, but will not be able to submit your Phase 2 sheets on time, please contact the queue working group.
8. For observations using narrow-band filters, the observatory will acquire standard star frames just before or after science exposures by 'default'. Standard stars will be selected from a list of spectrophotometric standard stars and the data will be shared with all relevant PIs. Time spent on the 'default' standard star data acquisition will not be charged.
