Does run_tclean need just the .psf directories or does it need more than that? Tclean will need all image types (suffixes) for the named image. For instance Task01 makes a set of 'iter0' images, task04 makes an 'iter1' set of images. Task 5 references both. It would be acceptable to pass images of iter0* and iter1* but in practice it only needs the PSF from both so something like iter0*.psf and iter1*.psf should work.
Is it safe to assume I don't need to transfer lockfiles like table.lock even if they have been modified?
How do we transfer input files for each DAG?
