Important Notice for S17B
- From S17B, HSC queue mode is opened for Intensive programs as well as Normal and Filler programs.
- Time critical observation is offered to Normal and Filler Program.
- No cadence program is offered.
- HSC queue mode programs will be executed in queue observation nights and in dead time ('Sukima time') in HSC classical mode programs. For this purpose, no additional target request in HSC classical observation is allowed.
- We had to spend about 40% of open-use HSC queue exposure time for filler program in S16B due to bad weather and realize the need of more filler programs in the queue. We encourage PIs to consider to submit filler proposals.
- Due to the degradation of reflectivity of the primary mirror, maximum possible transparency appears to be about 0.7 and 0.8 in g- and i2-bands, respectively. This will be improved after the mirror recoating expected to be finished by the beginning of December 2017. Please consider this effect at Phase 1 if your preferred month is before December 2017.
What is the HSC queue mode?¶
Queue mode is non-visitor mode observation, i.e. the observations are carried out by observatory staffs without a direct involvement of investigators (PI or Co-Is). The observation will be performed based on the rank of the observation program, the priority of the target, observing conditions (seeing, transparency, moon phase, moon distance, airmass of target), telescope slewing time, current instrument configuration (filter etc.) Appropriate selection of science objects with proper observing conditions allows to increase the effectiveness of the observation and data quality for better scientific outcomes.
Program selection and preparation consist of two parts, namely, Phase 1 and Phase 2. Phase 1 is the submission of proposals. PI should describe the observing condition constraints such as acceptable range of seeing, transparency, moon phase etc. in their proposal. Phase 2 happens after the proposal's acceptance by TAC (Time Allocation Committee). The PI will be notified and asked to prepare and submit details of their observation plan (as a list of observing blocks) before the beginning of the observation semester.
Subaru Telescope will manage the scheduling and execution of queue programs. The obtained data will be delivered to PI after the quality assessment.
Summary of Procedure¶
|Process||What should be done by PI||What should be done by the observatory|
Aug.-Sep. (A semesters)
Feb.-Mar. (B semesters)
The PI should submit a proposal via ProMS (Proposal Management System) as they do for classical programs. The observing condition constraints such as seeing, transparency etc. should be specified in the proposal.
Nov.-Dec. (A semesters)
May-June (B semesters)
|Observing block (OB) submission.
OB is the smallest unit of observations in queue mode. Using tools Subaru Telescope provides, the PI should complete the OBs before the deadline.
|Observation||Observations will be executed by observatory staff. After the data acquisition, the PI will be notified which OBs have been observed.||
|Data Delivery||When the data are ready for download, the PI will be notified with an instruction on how to obtain the data.||Subaru Telescope will provide the raw science data as well as associated calibration data and observation logs.|
