HSC



Information for S16B applicants:

Hyper Suprime-Cam (HSC) will be offered for open use in a shared-risk mode. Remote observations conducted from the Hilo Base Facility are not available.

HSC queue mode will be opened for Normal program in a shared-risk mode. Please see detail information at the 'HSC Queue Mode Webpage'. Note that the HSC queue mode will NOT be opened for Keck/Gemini time exchange, and University of Hawaii time programs.

Additional target request for filling dead time ('Sukima time') in HSC classical mode programs are NOT allowed. We will execute HSC queue mode programs in the dead time in HSC classical mode programs.

In S16B, there will be at most 5 observing runs (allocated to dark or dark-gray nights in late July and late October through January).

NB387, and NB718 filters are newly opened from S16B. If you want to use narrow-band filters, you may need to obtain an approval in advance from the filter developer team. See 'Available filters and sensitivities' for detail information and contact addresses.

The HSC SSP team will use NB387 in late October - early November, and NB921 in late December - early January.

The filter exchanger unit (FEU) of the HSC can hold up to 6 filters in one observing run. If you plan to use narrow-band filters for your observation, please consider the predetermined filters by the HSC SSP observation described above. Please note that there is a high probability that all broad-band filters (grizY) will be demanded by open use programs assigned at each month, in which case only one narrow-band filter can be used in each observing run.

The HSC development team is going to carry out 0.5 night Guaranteed Time Observations (GTO). The target list of the GTO is as below.

Target RA(hours) Dec(degrees) Filter
Abell851 9 +47 z, Y, NB921

HSC proposers who request to observe the same fields as aimed in the HSC SSP are required to explain the differences between your program and the HSC SSP. Please find the SSP fields from the web page of the HSC SSP.

HSC proposers must explicitly describe the filters they intend to use in Entry 16 'Instrument Requirements' (in the application form), where the desired set as well as the minimum acceptable set should be clearly specified. Please note that the filter exchanging system of HSC can hold up to 6 filters in one observing run.


Introduction

The Hyper Suprime-Cam (HSC) is a gigantic mosaic CCD camera, which is attached at the prime focus of Subaru Telescope. The HSC uses 104 main science CCDs, which covers 1.5 deg FoV in diameter with a pixel scale of 0.17", as well as 4 CCDs for auto guider, and 8 CCDs for auto focus.

It takes about 30min for changing filters. When we exchange filters, it is necessary for us to move telescope to the zenith position, and rotate the instrument rotator to the appropriate angle (∼0deg). we also close the cover of the primary mirror for safety operation.

When you cosider to produce new HSC filters, please read the filter policy carefully, and contact Subaru Telescope (new development group: newdev_at_naoj.org) well before applying for funds. Also, please refer the procedure to determine filters for each HSC run.
