Elements of the Portal Graphical User Interface
Direct your browser to https://mast.stsci.edu/ to use the MAST Portal web application. The Portal graphical user interface (GUI) is annotated in Fig. 1 and described in the following sub-sections.
The Search Panel is the only panel visible at the beginning of a session, apart from a Home Page with status information, until a successful search is executed.

Search Status and Action Bar
The results of each search are preserved during a Portal session. View each search by clicking the tab at the top of the search results panel. The footprints from all searches will appear in AstroView.
If the search is successful, the number of matching records, the (resolved) target name, the target coordinates (if the target name in the action bar is clicked), and the search radius will be displayed in the status area above the results table. Buttons in the Action Bar (to the right) provide additional functionality, as described in Search Results Grid.
The Filters Panel enables a finer selection of matching observations using values or ranges of select metadata.
Observations in MAST that match the search criteria, as modified by the selections in the Filters Panel, are presented in a table, like the one below.
User-facing metadata for the observations are presented in separate columns; you may show or hide individual columns by clicking the Edit Columns... text and checking boxes next to the column names of interest. These choices will persist for the duration of your Portal session. Preview images will be displayed (if available, as they are in the figure) for each row by checking the Show Preview box at upper right.
Availability of previews
Preview images are not produced for certain types of data (e.g., long-slit spectra). Previews will not be displayed for Exclusive Access data except for authorized users.
Advanced Search Interface
The advanced search window provides a way to fine-tune a search using additional metadata, as shown in Fig. 2 below. Access this from the main Portal GUI by clicking the Advanced Search text.
Only a few MAST collections support an advanced search option.
The main elements of the advanced search are listed below, and explained in detail on the Advanced Search page.

Download Manager Interface
Clicking the basket icon will add one or more selected observations to the basket and bring up the Download Manager window. This GUI shows all files that are associated with each observation and provides various tools for selecting files of interest, and provides multiple methods to download the selected files. See the Download Basket page for details.
