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

as well as transmission curves below for estimating more exact throughput of each filter.

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.
