mFitExec - Re-project and mosaic your images, with background rectification

       diffs.tbl
              Overlap table generated by mOverlaps, the last column of  which  contains  the  filenames  of  the
              difference images generated by mDiffExec.

       fits.tbl
              Output table of difference parameters.

       diffdir
              Directory containing difference images.

       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.

       Runs  mFitplane  on  all the difference images identified by mOverlapsand generated by mDiffor mDiffExec.mFitExec creates a table of image-to-image difference parameters.

       First, diffs.tbl is generated for a collection of reprojected images using mOverlap.  Next, mDiffExec  is
       run  on those images to create output images in the subdirectory diffdir.  At this point, we are ready to
       run mFitExec:

       $ mFitExec diffs.tbl fits.tbl diff
              [struct stat="OK", count=42, failed=0, warning=0, missing=0]

       Output file: fits.tbl.

       OK     [struct stat="OK", count=n, failed=nfailed, warning=nwarning, missing=nmissing]

       ERROR  Cannot open status file: statusfile

       ERROR  Can't open output file.

       ERROR  Invalid diffs metadata file: filename

       ERROR  Need columns: cntr1 cntr2 plus minus diff

       -d     Turns on debugging

       -s statusfile
              Writes output message to statusfile instead of to stdout

       Generates  a  table,  fits.tbl,  containing  all  the  information generated by running mFitplane on each
       difference image.  nimages is the number of images for which this calculation was successfully performed,
       nfaied is the number that generated an error  condition  for  mFitplane,  nwarning  is  the  number  that
       generated  a  warning,  and  nmissing  is  the  number  of files that could not be found in the specified
       diffdir.
