HSC



Information for S15A 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.

In S15A, there will be 3 observing runs, which will be assigned for maximum about two weeks around new moon in March, May, and July. In total, maximum about 42 HSC nights will be available in S15A, including openuse, SSP, Keck/Gemini time exchange, and University of Hawaii time.

In addition to five broad band filters (g,r,i,z,Y), NB921 and NB515 filters are opened from S15A. If you want to use these narrow-band filters, you must obtain an approval in advance from the filter developer team. See 'Available filters and sensitivities' for detail information and contact addresses.

The NB921 filter is supposed to be used on March observing run by the HSC SSP.

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.
