On this page, we'll review each component of the Mission Search user interface. The example we will use This page provides an overview on how to use the MAST Mission Search to find MAST data collections. The description of each form component on this page is based on theHST search form: by design, other data collections will use the . Info |

Future Searches for other MAST mission data and collections will adopt the same or similar components. | When relevant, we will specify any Any components that are only available | in for specific data collections will be documented. |

FormTo guide discussion, it is helpful to define This chapter summarizes the field guide to the major components of the Mission Search form. There There are two three main areas: the front-page search form and , the search results table, and the download overlay. Each numbered box in these figures is described in a corresponding numbered subsection below.

Summary Of The Major Components: Front-Page Search Form
<200 pixel screenshot of the major component>
Image Added Figure 1 – The Search form window for Hubble, where numbered highlights correspond to areas where various search parameters and constraints are specified, and where searches are initiated. |
The search form is where users specify the search parameters and constraints to create their search. The available search options include:
Each field in this search form provides a tooltip as a quick guidance. Users can hover over each field with their mouse to see the tips. Specific functionality of each component is summarized below.

Description of what you can do within this component.
Perform a cone search by typing either an object name or the coordinates directly. Multiple object names, coordinates, or combinations of both are allowed by pressing 'return' or 'tab' keys after each object. Use the 'UPLOAD LIST OF TARGETS' button to upload a comma-separated file containing the object names, coordinates, or specific dataset IDs. Users can set the size of their cone search in arcminutes or arcseconds. This section is not required to conduct a search: users can leave it blank and search based only on other parameters. To start querying, click the Search bar at the bottom of the page. Note |
---|
Object names in this component are used only to resolve into coordinates using a name resolver. |

Use these fields to build advanced searches. Add search constraints based on the most commonly used observation parameters like instrument, proposal information, filter/grating, or start/end times. Each parameter accepts regular expressions, for example, greater than or less than for numerical fields or wildcard characters for string fields. If the default filters on the component do not include the specific parameter needed, see the 'Add Condition' section below for further search options.
Image Added
Use 'Add Condition' to further constrain the search. Search for a column based on names and descriptions, or scroll through the complete list in the 'Column Name' text box. The search condition can include numerical constraints or wildcard characters for string fields. Use the 'ADD ANOTHER CONDITION' button to add multiple constraints and columns.

The search bar is always located at the bottom of your screen. Clicking the 'SEARCH' button starts the search. Clicking the 'SHOW API QUERY' button generates a script using the Application Programming Interface (API) for MAST Mission Search, based on the search parameters entered into the form. This can be a great way to learn how to construct queries programmatically. Reset the form using the 'CLEAR FORM' button on the left.

Image Added Figure 2 – The results table after a search for Hubble data. |
The search results table contains observations that match the search parameters. If a list of targets (object names, coordinates, or dataset names along with other information) is uploaded, all uploaded parameters will be included as additional columns in the results table. See the section Cone Search And Upload List Search for valid file formats.

Image Added Figure 3 – The download overlay panel, with selectors or action buttons highlighted in numbered boxes. The overlay selectors vary slightly among missions; this graphic applies to JWST. |
Each dataset contains one or more products (i.e., files), including calibration files, ancillary data, and calibrated files at various levels of processing. It is possible to download specific file types across the datasets or all the files that are available. The download overlay allows filtering by product types, and selection of specific files to download from each dataset. Files that are selected using the checkboxes remain selected to be downloaded even if additional filters are applied in the overlay to make them no longer visible in the overlay. The selectors and action elements are described in detail in the Download Overlay article
