Dear Gadget2-Users,

I am a "Gadget2 beginner" and I have read in the paper (Springel 2005) that
" Radiative cooling and heating by photoionization has been implemented in GADGET-2 in a similar way as in Katz et al. (1996),
i.e. the ionization balance of helium and hydrogen is computed in
the presence of an externally specified time-dependent ultraviolet
background under the assumption of collisional ionization equilib-
rium. Yoshida et al. (2003) recently added a network for the non-
equilibrium treatment of the primordial chemistry of nine species,
allowing cooling by molecular hydrogen to be properly followed."
but the cooling does not seem to be included in the publc released version.
Where can one find more details about the cooling implementation? Thanks a lot for your help.
