NAME

       mArchiveList - Retrieve a list of archive images from the IRSA server

SYNOPSIS

       mArchiveList survey band object|location width height outfile

DESCRIPTION

       Given a location on the sky, archive name, and size in degrees, contact the IRSA server to
       retrieve a list of archive images.   The  list  contains  enough  information  to  support
       mArchiveGet downloads.

ARGUMENTS

       survey Can be one of:

              2MASS DSS SDSS DPOSS

       band   Case insensitive - can be one of:

              (2MASS)  j,  h,  k  (SDSS)  u, g, r, i, z (DPOSS) f, j, n (DSS) DSS1, DSS1R, DSS1B,
              DSS2, DSS2B, DSS2R, DSS2IR

       object|location
              Object name or coordinate string to be resolved by NED (if string includes  spaces,
              must be surrounded by double quotes)

       width  Width of area of interest, in degrees

       height Height of area of interest, in degrees

       outfile
              Path to output table

RESULT

       [struct stat="OK", count=num-images]

       outfile  is  an  ASCII table of image metadata for the region and survey of interest.  The
       last column in the table is a URL that mArchiveGet can use to retrieve the image.

MESSAGES

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

       ERROR  Can't open output file outfile

       ERROR  Error message from IRSA's ImgList service

       ERROR  Couldn't find host hostname

       ERROR  Couldn't create socket()

       ERROR  hostname: connect failed

EXAMPLES

       To retrieve metadata and file handles for 2MASS J-band images, covering a  half-degree  by
       half-degree area around m31:

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

       Output file: 2mass_m31_j.tbl.

       To retrieve GPFS file handles for SDSS u-band images:

       mArchiveList -s gpfs sdss u m101 0.2 0.2 sdss_m101_u.tbl
              [struct stat="OK", count=16]

       Output file: sdss_m101_u.tbl.

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.
