Issue RCAL-847 was created on JIRA by David Davis:

The source catalog step needs to accept an input association. It currently fails with

We talked about this a little on Thursday. Because the L3 source catalog gets run after resample, I think we decided that we do not need to accept an input association. Dave, if you agree, could you close? Thanks!

Comment by Mairan Teodoro on JIRA:

As it has been decided that the SourceCatalogStep should not accept an association file as input, this ticket has been closed with no work.
