A Dataset ID marks a "top-level" collection of files from an Observation. The naming convention follows a truncated version of the full JWST file naming scheme; each filename in the dataset will begin with the dataset ID, followed by indicators for the detector used and product type.

The Data Type refers to the semantic content of the highest-level pipeline product for the type of exposure that produced the data. Note that slitless and IFU spectral modes ultimately produce data of type Spectrum.

Other data includes internal calibration and guide-star data.

By default, all Instruments are selected. The upper right of the field presents a Select all vs. Deselect all choice. You can also select individual fields.

Enabling the Moving Targets flag will only return targets without fixed coordinates (i.e. solar system targets).

 

The Observation Mode selector is empty by default. Note that searching for "all" and "none" are equivalent, as all observing modes will be included in both cases. This mode does not include type-ahead, so you must select your choice from the drop-down menu.

The Observation Number and Visit Number correspond to planning information from the submitted APT file. You can find the APT file, as well as a PDF summary, by searching for the corresponding proposal on the JWST Program Information search form.

Proposal Cycle is the number of the JWST Proposal Cycle in which the program was submitted and approved. This does not necessarily correspond to the epoch of the scheduled observation.

Proposal Type is the programmatic category assigned to the proposal. There are several Categories of JWST Science Observations.
