The following tables list filters available for open use observation of the HSC, together with their sensitivites. The transmission curves measured at the center of filters are available as plots and ASCII lists in the respective columns.
You may need to consider
Sensitivities listed are for a 5 sigma detection measured in a 2'' diameter aperture in 1 hour of integration, assuming good (0.5'') seeing, dark (New Moon), and clear sky (tranparency is 1.0). Please refer to the Exposure Time Calculator for sensitivities with other conditions.
(1) We replace the r-band filter to new one (HSC-r2) from Jul 28th 2016 (HST). We mainly used the previous r-band filter (HSC-r) till Jul 11th 2016 (HST). Please see "FILTER01" at the FITS header for checking which filter was used.
(2) We replace the i-band filter to new one (HSC-i2) from Feb 2016. We mainly used the previous i-band filter (HSC-i) till Jan 2016. Please see "FILTER01" at the FITS header for checking which filter was used.
(3) When you estimate a throughput of the Y band filter, you should consider the quantum efficiency of FDCCD, which is very low at >10000 Å.
(1) For user filters, during the first three semesters (or 3 call for proposals) after it is open to the public, people who are interested in using the filters must obtain an approval in advance from the filter developing team (cf. filter policy).
(2) If the semester is not passed, you must obtain an approval in advance from the filter developer team before you submit your proposal using these user filters. See 'Contact addresses of user filters. You need to explicitly describe that you have obtained an approval in your proposal.
(3) The NB656 is produced by the HSC developer team as a common use filter. You can use the NB656 without obtaining permission from S16A, when it is opened.
Contact addresses of user filters (1) and Information for acknowledgement(2)
(1) Subaru Telescope accepts user filters. When you cosider to produce new HSC filters, please read the filter policy carefully, and contact Subaru Telescope (new development group: ) well before applying for funds.
(2) In a publication using these filters, please add the acknowledgement. For example, the acknowledgement for NB387 will be as follows.
