    Data Acquisition

    Data file acquisition is the result of a 3 step process:
    (1) user specifies the record selection criteria using the query input form;
    (2) user reviews, and optionally edits, the logical query generated from the input form;
    (3) on display of the selected record summaries, the user selects

  • display of a complete Observation record;
  • display of a partial Observation record - lacking the PSF and transformation parameters for Macho Project chunks;
  • retrieval of an Observation image.

    Browser Setup Prior to File Retrieval

    In order to immediately display fits image files on your local workstation, setup your browser to invoke a fits image display tool on receipt of files ending with .fits. Tools which understand fits images include: ximtool, xv, iraf, and saoimage.

    For example, assuming a Netscape browser, select:

  • titlebar: Options
  • menu item: General Preferences...
  • folder: Helpers
  • task: New...
    Add the new entry:
  • image/x-fits ximtool %s > /dev/null 2>&1
    Of course, you'll need to have ximtool in your search path.
