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.
You may need to consider
- Quantum efficiency of FDCCD
- Transmittance of the Primary Focus Unit
- Reflectivity of the Primary Mirror
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, and
those for the SDSS filters, and a Y filter are on the AB magnitude system.
