COSMOS Filters

This is a compolation of filters for the COSMOS project. Ground based filter transmission curves are Filter + Optics + Mirror + Atmosphere + Detector, while space based Transmission curves are Filter + Optics + Mirror + Detector. All files have wavelength units of Angstroms and transmission units of photons (QE).

SDSS

SDSS Telescope Filters from the SDSS DR3 Camera Page These are at airmass of 1.3.


2MASS

2MASS Telescope Filters from the 2MASS Facilities and Operations pages These are the 0.5mm water vapor atmosphere curves


CFHT-MegaPrime

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 site.


Subaru Suprime-Cam

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.



NEWFIRM

NEWFIRM-IA band filters provided with EAZY. Ks band filter from NOAO NEWFIRM page + the 2MASS atmosphere.


VISTA-VIRCAM

These filter curves were taken from the VIRCAM Instrument page and include the atmosphere and the instrumental response.


GALEX

Galex Filter Transmission Curves in units of QE from Morrissey et. al. (2004)



Spitzer

IRAC Transmission Curvevs from the IRAC Instrument page

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.

MIPS 24um0.036
MIPS 70um0.076
MIPS 160um0.039

Herschel

Transmission Curvevs provided by the GTO teams
