Photometry

asteca : Membership probability catalogs (from .gst) derived using ASteCA (ascii)
asts : Culled columns from artificial star test files from DOLPHOT (ascii)
obs : Re-reduced HST observations via the UW Photometry Pipeline. These are the .gst catalogs level. (Binary fits tables)

Filenames are _ separated values of HST proposal id, cluster name, and filterset.

Columns:

ASteCA: RA, DEC, mag, e_mag, col1, and e_col1 are taken from the binary fits tables. These files have been culled by ASteCA to within the cluster radius.

ID : index
x : RA
y : DEC
mag : magnitude1
e_mag : mag1 err
col1 : color
e_col1 : color error (quadrature mag errs)
memb_prob : membership probability
sel : selection

ASTs:

mag1in : input magnitude1
mag2in : input magnitude2
diff1 : input magnitude1 - output magnitude1
diff2 : input magnitude2 - output magnitude2

obs : For information on how to read binary fits tables see astropy.

Columns:

For each filter listed in the filename, the following columns exist:

   [filter]_RATE                            
   [filter]_RATERR                          
   [filter]_VEGA : vegamag
   [filter]_STD
   [filter]_ERR : vegamag err

The following refer to DOLPHOT flags (see DOLPHOT readme file)

   [filter]_CHI
   [filter]_SNR
   [filter]_SHARP
   [filter]_ROUND
   [filter]_CROWD
   [filter]_FLAG
