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


       mProjExec  [-q] [-p rawdir] [-d] [-e] [-X] [-b border] [-r restartrec] [-s statusfile] [-x
       scaleColumn] images.tbl template.hdr projdir stats.tbl


       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.


       -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

       -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.


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

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

              Directory in which to create reprojected images.

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


       [struct stat="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


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

       ERROR  MPI initialization failed

       ERROR  Path (outdir) is not a directory

       ERROR  Restart index value string n cannot be interpreted as an integer

       ERROR  Restart index value n must be greater than or equal to zero

       ERROR  Cannot open status file: statusfile

       ERROR  Can't open output file.

       ERROR  Can't open tmp status file.

       ERROR  Can't delete tmp status file.

       ERROR  mProject or mProjectPP error


       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.


       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.
