TOOLS HELP Viewer browse CatsEye plot IMPReSS observations What's New Tutorial Feedback

• Impress (Footprints of images) is now up and running, but only Hubble ST observational data has been updated.

• The entire ADC site has been ported to the Astronomy Dept. at the U. of Maryland. The Viewer and CatsEye scripts are now operating again. IMPReSS will come next. There have been no new tables inserted into the ADC since it closed in 2002 and there is no funding at present to resume ingest. This site at http://adc.astro.umd has the full set of tables ingested over 25 years of operations at ADC. We have another site http://archive.astro.umd.edu/archive that was our experimental XML archive site. That site has most of the popular tables natively in XML, uses an object-relational database and it uses advanced XML processes in the viewer cgi scripts. It is the preferred site for most tables and especially for very large ones.

ADC Viewer:

• Non-numeric fields can now be constrained by Perl regular expressions.
• Javascript now catches common errors - no more waits for some error messages.

ADC Viewer:

• Users can now bookmark a specific Field selection page (in which you select the fields to view for a given catalog and file).

  We saw errors produced that look like users were attempting this, and since it's a good idea, we modified the software to allow it. Hope it helps!

Added a few modifications to ADC Viewer:

• Downloaded files now include a header with commented documentation, so you can now know what those mysterious lines are. Here's an example.
• Some buttons on the cull page have been renamed to reduce confusion:
  • Rename Table (was Save Table): Changed to reflect that you are only renaming the table in your workspace, not saving it to your disk (use Download for that).
  • Your Tables (was Saved Tables): Changed to emphasize that the pull-down menu holds your tables saved in your workspace.

The ADC Viewer has undergone an extensive internal software rewrite, and you'll notice a few minor (but helpful) differences:

• Home page: The Viewer top page has been slightly modified, and is available in both verbose and terse versions.
• Names: Catalog and file names are displayed at the top of the pages.
• Sort: Ascending/descending sort available as separate links for each field of your table display.
• Workspace: Previously saved tables can be viewed, downloaded, or deleted from your personal work area.
• Direct access: You can go directly to your workspace if you already have one (by having created a Viewer table within the last 5 days).
• Display: You can stop the browser's display before it's finished without breaking the software (in case you get tired of waiting for the full table to appear).
• Blanks: Specified blank values for a given field are now assigned the lowest possible value for that format (e.g. an F5.2 blank would be -9.99).
• Pre-processing: Most catalogs are now available for viewing without processing wait (we're working on the journal tables next).
• Performance: Software performance should be more stable, with fewer errors.
• AEQ: a non-interactive version of the Viewer is now available.
• Scripts have been renamed (FYI only - no need to remember them):
  • select.pl (was adc_viewer_1.pl): Choose table from available tables in catalog
  • specify.pl (was adc_viewer_2.pl): Choose fields and limits
  • cull.pl (was adc_viewer_3.pl): Culls and displays requested table
