Notes. The error in the solid angle σΩ comes from the scanning beam error budget. The spatial variation ΔΩ is the rms variation of the solid angle across the sky. The reported FWHM is that of the Gaussian whose solid angle is equivalent to that of the mean effective beam. Ω1 and Ω2 are the solid angles contained within circles of radius 1 and 2 FWHM, respectively (used for aperture photometry as described in Appendix A of Planck Collaboration XXVIII 2014).
