Component Overview
The 'HST Search Parameter Components' section contains the common search parameters for the Hubble data collection. This page overviews the types of search components and how to specify parameter constraints.
Parameter Constraint Syntax
Learn how to specify constraints on search parameters depending on the nature of the input. The following specifications apply for the core search parameters and Additional Search Parameters in the search form.
Hovering over each filter box shows tooltips on how to use search conditions.
HST-Specific Search Components
Dataset ID
The 'Dataset ID' is a unique dataset name. For HST, it is 9-characters long, e.g., J8BA7JCAQ or O4140Q020, where the first character indicates the instrument used: L=COS; I=WFC3; J=ACS; N=NICMOS; O=STIS; U=WFPC2; W=WFPC; X=FOC; Y=FOS; Z=GHRS; F=FGS; V=HSP.
This component is a String field, so 'Exact Match', 'Wildcard', 'Exclude', and search by 'Multiple' entries are allowed. If known, type the exact dataset ID into this field's box. If the exact dataset ID is not known, conduct a wildcard search or type a string to enable a type-ahead menu. It will show a list of dataset IDs that contain that text. Browse through the suggested list to find the right one by scrolling the mouse or use the scroll bar on the right of the menu, and then click to select.
Data Types
By default, the 'Data Type' is set to 'ALL'. Check the check box for a preferred data type: 'SPECTRUM' or 'IMAGE'.
Instrument Selector
This video clip demonstrates how to select different instruments to include in searches.
Some data collections contain datasets from a wide range of instruments, for example, the various HST instruments. Mission Search can include results from across all available instruments or a subset of them. By default, all available instruments are selected. Hovering the mouse over each instrument will show the full name of the instrument.
Depending on the 'Data Types' selection, such as 'SPECTRUM' only or 'IMAGE' only, the list of available instruments will also change (an instrument that only takes images will not be shown if only 'SPECTRUM' data types are selected, for example). To select a single instrument, click the 'none' (
) button and then select the desired instrument to include.
Some instruments produce neither images nor spectra: the Fine Guidance Sensors (FGS, which produce astrometric, usually interferometric, data) and the High Speed Photometer (HSP, which produced photometric data). These instruments will only appear if 'ALL' is selected in the Data Types area.
Observation Type
The 'Observations' selector can choose 'SCIENCE' and/or 'CALIBRATION'. The default setting is to search only 'SCIENCE'.
