Algorithm

 get and create the archive root directory 

 get a list of file names in the current working directory.

 sort the file names according to observation, exposure, window and file type.

 run the pipeline.

 for each orbit

    print orbit being processed

    for each slew  observation 

        print Slew Observation being processed 

        construct a list of filenames for:

            raw images
            combined images
            mod8 combined images

        for each exposure

            print exposure being processed

            check to see if Window Data File is present

            set pipeline variables.

            for each window data file

                prepare images for pipeline using omprepslew

                add filenames for 

                    raw images
                    exposure image
                    raw exposure images

                to appropriate lists

            end window data files

            make archive subdirectory (if it does not exist)

            construct file names

            produce tracking history products using omcomb

            copy combined image to archive

            produce bad pixel map for ommodmap(see below) using omcosflag

            correct images for modulo-8 noise using ommodmap

            remove fixed pattern noise using ommattmodmap

            add mod8 combined file name to list

        end exposure

        update index using omflatindex

        remove work files

    end observation

end orbit
