The parameters for a list of sources can be stored in a text file, which omphotom can access through the parameter paramfile. This method also allows sources from different images and source-list files to be reprocessed. Blank lines will be ignored and any error found in the file will be reported and the program stopped- the error message may indicate where the ``error'' in the file is.
An example parameter file is shown below, the line number on the left (not in the file) corresponds to that in the section notes
