I think the way to implement this is to give the option to pass a list of column names that are in the parameter list that would be included in all of the analysis files, but don't actually have any fittable parameters.
The Generate_FitParam_File class now has a variable called additional_columns that takes a list of column names that are in the parameter linelist to pass through
