New release of ChaSeR and WebChaSeR

2002-02-13

New versions of our archive search and retrieval tools have been released, with mainly bug fixes for ChaSeR and enhancements for WebChaSeR.

ChaSeR:

  • In Detail display data and label were misalligned following OCAT modifications for NRA4; this has been fixed.
  • Reset button on query form now clears all entries and restores the default query constraints.
  • ChaSeR will return with an error when the connection to the server fails.
  • Prevent server error on search with all checkboxes unchecked.
  • Add row number to observation search results table.
  • Parse/validate format of entered value for radius and prevent server error on wrong input.
  • Disallow login with blank username and password.
  • Fixed problem with public release date not displayed.

WebChaSeR:

  • Support password change.
  • Added Name Resolver option using SIMBAD.
  • Added choice of coordinate system and format for input and output coordinates.
  • Limited to 50 the number of obsids selected for browse/retrieve data (still coming: information message to user).
  • Hide ftp path of retrieved data while the tar files is being created.
  • Added numbers to displayed obsid rows.
  • Added row number to Browse results table.
  • Added choice of ascending/descending sort order for displayed obsids.
  • Fixed problem with public release date not displayed.
  • Added support for change password.
  • Disallow login with blank username and password.
  • Generate a validation error on Browse/retrieve with both Primary and seconday unselected.
  • Dynamically configure WebChaseR for installation at any server.
  • No crashes on Search if everything is unselected.
  • Parse/validate format of entered value for radius and prevent server error on wrong input.
  • Error in one input field does not clear form anymore.

Two caveats are being added:

  • Selecting a range in galactic coordinates works reasonably well for small rectangles, as long as one stays away from the poles. Large ranges and ranges covering the polses may give surprising results.
  • For certain ObsIds retrieval of secondary and/or supporting products (e.g., aspect solutions) may not return all products that are required.
