New, Updated and/or Revised HEASARC Xamin and Browse Databases For The Current Year

The following list is of databases now accessible via Xamin and Browse that have either been newly created and/or substantially updated, or are updated 'master' catalogs (as indicated by being in bold characters), or were slightly revised or are regularly updated (normal characters). This list, which is updated approximately once a week, is in reverse chronological order, i.e., the most recently created/updated databases are listed first. For any given table, typically only the most recent update is listed.

To see the online documentation for a database, click on the database name; there is a link in the top left-hand corner of this new page that takes you to a Browse form in which you can query the table in question.

A list of database tables that have been deleted is available here.

A list of project tables that are regularly updated is available here.
