Notes. The given area is the size used for the CIB power spectrum computation (i.e., removing the area lost by the masking). The “GASS Mask2” is not used for CIB power spectrum analysis but for some tests on the quality of our component separation, and for the measurement of the bispectrum. Mask2 includes all of Mask1.
