SZ effect maps

The “y_theta_NNN.fits” maps are maps of the Compton y parameter from the SZ effect for \sigma_8 = 0.825 using fiducial gas physics. The maps are 3×3 degrees in size, with 600×600 pixels, and are in FITS format. Their creation is described in Peel et al. (2009); they can be converted to a given frequency using equation 13 in that paper, and can be scaled to other values of \sigma_8 (such that the power spectra agree) using sigma_8^(7/2).
