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


       mFitExec [-d] [-s statusfile] diffs.tbl fits.tbl diffdir


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


       -d     Turns on debugging

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


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

              Output table of difference parameters.

              Directory containing difference images.


       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.


       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

       ERROR  svc library error


       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.


       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.
