This page contains a list of broad-, intermediate- and narrow-band filters from ground and space that are used by the COSMOS survey. For each filter we also provide the filter transmission curve (throughput vs. wavelength in Angstroms) for download. Ground based filter transmission curves are Filter + Optics + Mirror + Atmosphere + Detector, while space based Transmission curves are Filter + Optics + Mirror + Detector. All transmission curves are given in units of photons (QE). The wavelengths given in the tables are computed as the median wavelength weighted by transmission.

Spitzer
IRAC Transmission Curvevs from the IRAC Instrument page. 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.
