NAME

       mArchiveGet - Retrieve a single FITS image from a remote archive

SYNOPSIS

       mArchiveGet [-d] [-r] remoteref localfile

DESCRIPTION

       Retrieve a single FITS image from a remote archive, using a basic URL GET but with a structured output.

OPTIONS

       -d     Print additional debugging information.

       -r     "Raw"  mode  -  use  a raw HTTP GET (no "HTTP/1.1" etc in the header); necessary for communication
              with some servers.

ARGUMENTS

       remoteref
              URL of remote FITS file to retrieve (should be in quotes).  See mArchiveList for more information.

       localfile
              Full path/filename of the retrieved file.

RESULT

       [struct stat="OK", count="bytes"]

       If remoteref points to a g-zipped 2MASS QuickLook image, the image will be unzipped during transfer.

MESSAGES

       OK     [struct stat="OK", count="bytes"]

       ERROR  Output file (localfile) open failed

       ERROR  Invalid URL string (must start 'http://')

       ERROR  No data reference given in URL

       ERROR  Illegal port number in URL

       ERROR  Illegal return from select()

       ERROR  Connection timed out

EXAMPLES

       $ mArchiveGet "http://irsa.ipac.caltech.edu/cgi-bin/FileDownload/ nph-
       download?raw=1&ref=/ti08/971024n/s009/ image/j10090244.fits.gz" j10090244.fits
              [struct stat="OK", count="2111040"]

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.
