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

       images.tbl
              ASCII table (generated by mImgtbl) containing metadata for all images to be reprojected.

       template.hdr
              FITS header template to be used in generation of output FITS.

       projdir
              Directory in which to create reprojected images.

       stats.tbl
              Name of table for output statistics (time of each reprojection, or error messages).

       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.

       An executive which runs mProject (or, if possible for the input/output projections, mProjectPP) for  each
       image in an image metadata table.   In the case of data cubes, mProjectCube will be used.

       The following example runs mProjExec on a directory containing 16 images. The -f  switch  specifies  that
       mProjExec  will  use  mProjectPP  to  reproject  the  files,  as  opposed to mProject. Relevant files are
       images.tbl, generated by mImgtbl, and template.hdr.  Files will be created in the directory projdir.

       $ mProjExec -p raw images.tbl template.hdr proj stats.tbl
              [struct stat="OK", count=16, failed=0, nooverlap=0]

       See output file stats.tbl.

       OK     [struct stat="OK", count=nimages, failed=nfailed, nooverlap=noutside]

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

       -q     Use mProjectQL for reprojections.  Much faster but not quite flux-conserving.

       -p rawdir
              Specifies  the path to the directory containing the images to be reprojected.  If the -p switch is
              not included, mProjExec looks for the images in the current working directory.

       -d     Turns on debugging

       -e     Flag indicating output image should exactly match the FITS header template, and not crop off blank
              pixels

       -X     Force reprojection of whole images, even if they exceed the area of the FITS header template

       -b border
              Ignore border width of pixels around edge of images

       -r restartrec
              Allows restart at record number restartrec, if mProjExec exits upon an error

       -s statusfile
              Output and errors are written to statusfile instead of being written to stdout.

       -x scaleColumn
              Turn on flux rescaling (e.g. magnitude zero point correction): scaleColumn is the name of a column
              in images.tbl which contains scale information.

[structstat="OK",count=16,failed=0,nooverlap=0]

       For each input file name.fits in the table images.tbl, mProjExec creates a  corresponding  name.fits  and
       name_area.fits in the directory projdir.

       nimages  is  the  number  of  images successfully processed, nfailed is the number of images mProject was
       unable to process, and noutside is the number of images that did not overlap with the given template.hdr.

       The file stats.tbl is an ASCII table containing the filename, status, and time for each file.
