High Level Science Products are user-contributed observations, catalogs, or models that complement, or are derived from, MAST-supported missions. This page describes the HLSP Search form, which is one way to find HLSP product collections.
On this page...
The HLSP Search form described on this page is not the only way to discover HLSP collections. Many collections have had some or all of their data ingested into our multi-mission database, which is accessible from the Multi-mission Portal and Astroquery.
The search form
The HLSP Search form includes text-based search fields (within the box labelled 1) and tag-based search fields (2) which create filters to match against HLSP collection metadata. Buttons in the search bar (3) can reset the form or apply your search criteria.
Boolean logic
There is a Boolean AND
between individual search fields of any type. For example, if you search for "
HLSP Name Contains=TASOC
and Abstract Text Contains=cats"
, you will get no results, because no HLSP meets both criteria. Different Boolean logic applies within individual search fields, depending on the type: Boolean AND
within a text-based field, Boolean OR
within a tag-based field, as discussed below.
Text-based search fields
The HLSP Name and Abstract Text fields perform string-matching to HLSP names and abstracts, respectively. Within a single field, an HLSP must be a match for all space-separated strings that you enter (Boolean AND
), but these strings do not need to match whole words or be in any particular order.
Tag-based search fields
The Object Type, Mission, Product Type, and Waveband fields will filter on tags that have been attached to HLSPs. Within a single field, an HLSP project that is a match for any of the selected tags will be included in the results (Boolean OR
).
The search bar
Any filters you add will not be executed until you either click Filter Results or hit enter within a text-based search field. To clear all filters, click Clear Filters, which will also re-execute the search. A count of the number of results from your search is displayed below the Filter Results button. This number will not change until you execute a search.
