The first column is M15 (i.e. M_{200-crit} in units of 10^{15}Msun/h), the second column is the velocity dispersion of the particles within r_{200} in km/s, the third column is the inferred sigma15 (also km/s) through
(M/10^{15}Msun/h) = (sigma/sigma15)^3
If the run contains gas then the fourth and fifth columns are the mass weighted temperature within r_{200} in keV and kT15 defined through
(M/10^{15}Msun/h) = (kT/kT15)^(3/2)
These runs have no energy injection, and are done with the entropy conserving SPH scheme that Volker Springel invented.
The files contain only groups with more than 1500 particles in the FoF halo, which should be quite conservative. The averages and cosmologies are:

The first two simulations have 1024^3 particles (and the data are for halos with more than 5000 particles), the next four simulations have 512^3 particles, the next two 256^3, the next two 2x192^3. These two runs differ only in the random number seed used in constructing the initial conditions. The open CDM model and the varying w cosmologies use 256^3 particles (see below). All simulations use n=1.0 except ocdm256A, lcdm256A and lcdm128A which have n=0.95.
