Analysis of large-scale
Analysis of clusters
Analysis of turbulence
always needed to assemble ENZO's snapshots, needed because ./enzo.exe -x does not work for Nproc>64.
Developed by C.Gheller, all in serial.
produced for the varius machines used in these latest years [C.Gheller,FV]
IDL routines to produce first distribution functions of quantities as a function of T, rho (usefult for unigrid runs)
