root [2] TF1 *fun1 = (TF1 *)gPIP->Fnid;
gPIP->Fnid is the pointer to the function used to get PIP total multiplicity ( i.e. integrand ). x axis correspond to k/m and y axis are the integrand function.
This shows the parameters of the distribution.
Par 2 = eta ( 1 for Fermi stat, -1 for Bose stat ).
If you like to access the model values, you can try
root [5] thermal->PrintInfo(0);1~9
Each one explains what is being printed...
