MAST Staff - 2023 Mar 27

 

The names of the JWST science instruments, as viewed in MAST, have been supplemented with configuration information.  This change enables you to target your searches more precisely in the Portal and using the astroquery.mast API, compared to using the instrument name alone.  It also makes the instrument search criteria more similar to that for HST.

The standard JWST instrument names are listed in the table's headings, and the possible Instrument name+configuration variants are given in succeeding rows.  Data from FGS are also searchable, but this instrument name has not been augmented.

Please noteSoftware to extend the instrument names was installed at the beginning of 2023 March, but the results will not be fully realized until all JWST data in the archive have been reprocessed. This mixed state of old and new conventions will likely persist through early April. Until then, we recommend using a wildcard at the end of an instrument name to be certain of searching for all data for that instrument.

For more details, see the article JWST Instrument Names.
