mCatMap - Point-source imaging program

       in.tbl Input table of source metadata.

       out.fits
              Path of output FITS file.

       hdr.template
              ASCII header template defining output FITS file.

       The drizzle algorithm has been implemented but has not been tested in this release.

       If a header template contains carriage returns (i.e., created/modified on a Windows machine), the cfitsio
       library will be unable to read it properly, resulting in the  error:  [struct  stat="ERROR",  status=207,
       msg="illegal character in keyword"]

       It  is  best  for  the  background  correction  algorithms  if  the area described in the header template
       completely encloses all of the input images in their entirety. If parts of input images are "chopped off"
       by the header template, the background correction will be affected. We  recommend  you  use  an  expanded
       header  for  the  reprojection  and background modeling steps, returning to the originally desired header
       size for the final coaddition. The default background matching  assumes  that  there  are  no  non-linear
       background  variations  in  the individual images (and therefore in the overlap differences). If there is
       any uncertainty in this regard, it is safer to turn on the "level only"  background  matching  (the  "-l"
       flag in mBgModel.

mCatMap  is a point-source imaging program.  The user defines a general output FITS image, and its pixels
       are populated from a table of point sources.  The source fluxes (or just source counts)  from  the  table
       are added into the appropriate pixel to create an output image.

       To create an image showing the 2MASS point source fluxes (2mass_pt.tbl) in a 2 square degree area defined
       by 2mass_pt.hdr:

       mCatMap -c flux 2mass_pt.tbl 2mass_pt.fits 2mass_pt.hdr
              [struct stat="OK", time=4]

       Output image:

       OK     [struct stat="OK", time=seconds]

       -c column
              Name  of  the  table column that contains flux levels.  If not specified, pixels will be populated
              with source counts rather than summed flux values.

       -m refmag
              Set a reference magnitude to use when calculating fluxes.

       -d level
              Turn on debugging to the specified level (1-3)

       -w size
              Set a spread size for point sources (default is to use no spread).  Allowed values are 3 or 5.
