Poking around the disk that I have seadas installed on, I discovered in $ SEADAS/data/modisa/cal (and modist/cal) that the QA, emissive and reflective luts that are updated "automagically" by $ SEADAS / e t c /modis_update_luts.c s h aren't purged (ie I've got about 10 versions of each).  Is there any reason not to periodically go in and "clean up the stables"?

Cleaning up the tables is fine.. there was one instance in the past where a problem with a new table broke processing for current files, so it might be a good idea to keep a couple previous versions around just in case.
