N-body simulations show the log Compton-y distribution mean decreases linearly with neutrino fraction (slope ~10 f_ν) and tSZ power spectrum scales as power law in σ8^cb (exponents 7.3-8.1), with ∑m_ν=0.16 or 0.32 eV fitting Planck data better than massless case.

abstract
In Paper I, Greisen & Calabretta (2002) describe a generalized method for assigning physical coordinates to FITS image pixels. This paper implements this method for all spherical map projections likely to be of interest in astronomy. The new methods encompass existing informal FITS spherical coordinate conventions and translations from them are described. Detailed examples of header interpretation and construction are given.
