New Chandra Target Search Features

Link to Chandra Data Archive ADS search: clicking on the ObsID link will perform a Chandra Data Archive ADS search for papers relevent to that ObsID.

Continuous Clocking Mode Searches: one may now search with the ACIS exposure mode as one of the criteria, i.e. either Timed Exposure or Continuous Clocking mode may be chosen under "ACIS Mode".

Refined pattern matching: in any numeric fields, one may use the wildcard "*" to indicate that any digits may be matched at this end. This may be used within a comma-separated list. For example, if you enter in the ObsID field:

*222

the ObsIDs 122, 222, 2222, and 3222 will be returned. If you enter:

1,*672*

the ObsIDs 1, 2672, 672, and 1672 are returned. Also note that if you enter a number without the asterisk, it will do an exact match.
