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.
