Name: fpAtlas-rrrrrr-c-ffff.fit, where rrrrrr is the imaging run number, c is the column location in the Imaging Array of the CCD which acquired the data (1-6), and ffff is the field number within the run.

Size: This is a guess. Say 400 objects per field, with an average atlas image measuring 10x10 pixels. Then 665.28 Kb per file. One file per field. Total of 665.28 Mb for a single frames pipeline run with 1000 fields.
Archived? Yes. Tracked file.
