mArchiveExec - Call mArchiveGet on each image in sequence

       region.tbl
              Table of archive images, generated by mArchiveList.

       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.

       Given a table of archive images (generated by mArchiveList), calls mArchiveGet on each one in sequence to
       retrieve all the files into the current directory.

       First, run mArchiveList to generate a table of image metadata, including URLs:

       $ mArchiveList 2mass j m31 0.5 0.5 2mass_m31_j.tbl
              [struct stat="OK", count=18]

       Next,  call  mArchiveExec on the metadata table to populate the current directory with the files found by
       mArchiveList:

       $ mArchiveExec 2mass_m31_j.tbl
              [struct stat="OK", count=18, failed=0]

       $ ls

       -d level
              Prints out additional debugging information; in this version, the only supported level is 1.

[structstat="OK",count=num-images,failed=num-failed]num-images  from  region.tbl  are  retrieved into the current directory.  num-failed is a count of failed
       attempts to retrieve images; turn on debugging to see the errors generated by mArchiveGet.
