SPITZER, 2MASS, optical filtersets / bandpasses

Almost all of the information on this page can be found at the Spanish Virtual Observatory's Filter Profile Service; probably the only unique information here is Bolocam's bandpass.

Note that the central frequency reported is the effective central frequency for α = 3.5 or β=1.5. For different central frequencies and a detailed analysis, see the BGPS methods paper . Also, the high-frequency cutoff for MAMBO is slow and therefore poorly constrained.
