Data from White, Hernquist & Springel (ApJ, 579, 16). The FITS files are Compton y maps, 1x1 degree, 512^2 pixels from the highest resolution, heating, cooling and winds simulation. The gzipped tar file contains the group information for each slice of each field. Catenate all of the files with the same ending seed to obtain the full catalog. The group information is stored in ascii, the format is pixel number (x and y), distance (Mpc/h), mass (Msun/h), temperature (K), gas fraction (as a fraction of the universal value) and redshift of the output.
