The code needs an Input file describing the parameters to be fitted. An example of such an input file is nonext_freeall.inp.
to execute (must be in the folder with the data):
python ../src/cont_fit_mcmc_abso.py nonext_freeall.inp outputname [options]
To get help on the options do:
python ../src/cont_fit_mcmc_abso.py -h
with the options you can control the fitting parameters, number of MCMC steps, number of walkers etc.
In case of doubts let me know.
