Phase 2

Imporant Notices

  1. From S21A, the total time allocated by TAC includes the 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 less) is restricted 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.
  4. The standard star acquisition policy for narrow-band observations has been updated.
  5. Phase2 of Grade C and F programs will not have detailed reviews and iteration. The submitted version will be accepted as it is. If there are any obvious points to be corrected, we may modify the Phase2 without any notifications.

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

  1. Please contact queue (at) naoj.org if you have any questions. Support astronomers (SAs) will help your preparations.
  2. An OB is the minimum observation unit. The maximum length of on-source exposure time in an OB is limited to 30 minutes. 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 that starting from S19B we are limiting the number of the short exposures (60 sec or less) 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 PI's Document (PDF, HTML) for more details.
  4. Check OBs with the Web check tool. If there is no error, submit the Google Sheet through the Web check tool.
  5. Subaru Telescope will check the submitted OBs. Also, we will check the probability to complete the observation during the semester. SAs may ask the PI to relax the observing condition constraints in order to increase the probability of conducting the observation. If relaxing the observing condition constraints is possible, the PI should re-submit the OB list with relaxed conditions.

Important Policies for Phase 2

  1. Each OB must have on-source exposure time equal to or shorter than 30 minutes (1800 seconds).
  2. To facilitate scheduling, please choose one of the following constraints for seeing: 0.8, 1.0, 1.3, 1.6, and 100 (i.e., no constraint). Analogously, for transparency please choose one of 0.7, 0.4, 0.1, and 0, the latter corresponding to "no constraint". Regarding transparency, note that we define it as the total throughput including the telescope and instrument, and not just the atmosphere. The tolerance factor we use for these constraints is such that the numbers will be rounded off at the second decimal place (for example, seeing (transparency) 0.84 (0.65) for an OB requesting 0.8 (0.7) will be considered as good.
  3. Observing condition constraints for any OB must be no 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 PI's Document (PDF, HTML) 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 the observing semester starts, even if the PI is asked to relax constraints.
  6. For a scientific target without SDSS imaging data, the PI needs to provide the coordinates of a calibration field, not necessarily SDSS.
  7. Although the amount of actual observing time including overheads for a program will be equal to or shorter than the time allocated by the TAC, the PI may include OBs with the observing time larger than the time allocated by TAC. Depending on the extra OBs included, this may improve the probability of execution, but please note that the priority of the targets will not always be guaranteed, and the program will be considered as 'completed' when all of the observing time allocated by TAC has been used.
  8. 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 the Phase 2 sheet by the deadline, please contact the queue working group.
  9. For narrow-band observations, the observatory will acquire standard star frames just before and after the science exposures by 'default'. Standard stars will be selected from a list of spectrophotometric standards and the data will be shared to all relevant PIs.
    PIs will not be charged for the 'default' standard star frames.
  10. Starting from S19B, in case of proposals using both broad-band and narrow-band filters, once it becomes impossible to execute a narrow-band OB due to filter scheduling, the priority of the corresponding broad-band OBs will be lowered.
