Models without massive neutrinos

A range of initial spectra which have been computed by our Boltzmann code and fit with our fitting function (ea.20) are available. The fitting parameters are tabulated in the file cdm.fit. You will need to look in this file and determine the line number of the model which you are interested in. The first program (PMmodels) will ask to give you the following parameters:

Next you will run PMstartCDM which is the program that actually generates initial conditions for the PM code. It will generate two files, which PMmain reads and updates: PMcrd.DAT (information on the cosmological model and parameters of the run) and PMcrs0.DAT (coordinates and velocities of particles). If you run a CHDM simulation, you will have more data files with data for hot neutrinos. PMstartCDM will ask you to provide some parameters. If you created file InStart.dat using the program PMmodels, simply provide the file as input: PMstartCDM < InStart.dat .
