Suprime-Cam general filters
The following tables list the general filters available for general use, together with their sensitivites. The transmission curves of each filter are available as plots or ASCII lists if indicated in the respective columns.
The sensitvities and zeropoints for FDCCDs are still under investigation and will be updated when more appropriate values are available (2.4.2009).
Broad-band filters
Sensitivities listed are for a 5 sigma detection in 1 hour of integration, assuming good (0.5'') seeing and a moderately dark sky (3 days from New Moon). Point sources are measured in a 1.5'' diameter aperture; extended source sensitivities are per pixel; binning over N pixels will improve the sensitivity by 1.25 log N mag.

Magnitudes for the Johnson-Cousins filters are on the Vega system.
The SDSS photometric system is a slightly modified version of the
AB magnitude system. See Fukugita et al. (1996; AJ 111, 1748) for more details.
