NAME

       mArchiveExec - Call mArchiveGet on each image in sequence

SYNOPSIS

       mArchiveExec [-d level] region.tbl

DESCRIPTION

       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.

OPTIONS

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

ARGUMENTS

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

RESULT

       [struct stat="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.

MESSAGES

       OK     [struct stat="OK", count=num-files, failed=num-failed]

       ERROR  Table  region.tbl needs column 'URL' and can optionally have columns 'fname'/'file'
              and pixel ranges 'imin'...'jmax'

EXAMPLES

       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

BUGS

       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.
