The tso_photometry step has one step-specific argument:
--save_catalog
If save_catalog is set to True (the default is False), the output table of times and photometry will be written to an ecsv file with suffix "phot".
Note that when this step is run as part of the calwebb_tso3 <calwebb_tso3> pipeline, the save_catalog argument should not be set, because the output catalog will always be saved by the pipeline module itself. The save_catalog argument is useful only when the tso_photometry step is run standalone.
