Files have been moved to /datasets/decam/_internal as proposed (my previous comment on Jul 26 and a slight change to satisfy RFC-308). Unneeded files such as rerun attempts and non-fits files have been removed as proposed.
When I tried to remove the duplicates in Dey's COSMOS folders (20130209, 20130210, 20130211, 20130212), I found all 136 visits that have 'COSMOS' in its OBJECT header key are duplicates and were already added by
RFC-263. Other files in those folders seem to be raw calibration files, test exposures, or other non-COSMOS objects. Therefore, I propose to simply remove all of these folders (20130209, 20130210, 20130211, and 20130212) from /datasets/decam/_internal/raw/ if there are no objections.
