Filter Transmission Curves
Filter + Optics + Mirror + Atmosphere + Detector
All filters are in wavelength units of Angstroms and Transmission units of photons (QE)
SDSS Telescope Filters from the SDSS DR3 Camera Page These are at airmass of 1.3.

CFHT Telescope Information
CFHT Megaprime Filters from SAGEM multiplied by the CFHT mirror, Megaprime-Optics, and CCDs at airmass of 1.2. Information can be found at the CFHT Filter Page and the Megaprime we site.

Subaru Telescope Information
Subaru Telescope Broad Band Filters from the Suprime-Cam Filter Page which appears to no longer exist. These are at airmass of 1.2.

Subaru Telescope Intermediate Band Filters from the Suprime-Cam Intermediate Band Filter Page which is no longer in existance. Here is an internet archive backup of the intermediate band fitler page. These at airmass of 1.2 at the center of the filter.

Subaru Telescope Narrow Band Filters from the Suprime-Cam Narrow Band Filter Page which is no longer in existance. Here is an internet archive backup of the intermediate band fitler page. These at airmass of 1.2 at the center of the filter.

IRAC filter Plot
NOTE: The Spitzer IRAC photometric system is not on the AB system. IRAC is calibrated relative to nu*Fnu=Const rather than Fnu=Const. However the difference is neglagable for the IRAC bands.
MIPS Transmission Curvevs from the MIPS Instrument page converted to units of QE.
NOTE: The Spitzer MIPS photometric system are not calibrated on the AB system. MIPS is calibrated relative to a 10,000K black body. As a result there are zero-point offsets between the pipeline calibrated Spitzer data and the AB system. These offsets are given below and must be added to the measured magnitude. These corrections can be found on page 30 of the MIPS data hand book.
