This page contains information on how to use the SID MAST Portal to find, select and retrieve JWST Ground test data. 

Currently, the only way to download data from the SID archive is to download the data to an Archive staging area and then use Cyberduck (ftp client) to download the data to your machine from the staging area.

The portal contains a series of search boxes, or filters, in the main section of the page, with additional search options listed on the left of the page. To add one of the filters (options with green plus signs can be added), simply click on the search option you want. If it contains a red minus sign, you can remove the filter. This is customizable to allow the user to search only the options they wish. The download limit is 25000 files, so the selection should be narrowed down lower than this before trying to view/retrieve the files. Search Fields that are valid for packages have a '(p)' appended to their name.

The default set of search boxes are listed in the 'Primary' columns, while other options that can be added are listed under 'Secondary' columns.

Text box searching: Most search options have a blank text box that allows the user to start typing all or part of the item they're searching for.  To search for an option, just type part of it, like in Google, and the archive will retrieve anything with that text as part of the option. There are two wildcard options, for more detailed searches, the % for multiple characters and an underscore '_' for single characters.

Menu scroll searching: Many search boxes also contain menus of options that can be selected by scrolling through the list and selecting various options (multiple options allowed) by clicking on the boxes next to the desired selection. The options in the menus are not alphabetical, but organized by the number of files in that category, with the largest number of files at the top.

Once a user has selected the set of files they wish to view, the user should click on the download button at the upper left corner. This will display a window with all of the selected files. The filter panes on the left of this window can be used to further narrow the list of files displayed. From here, individual files can be selected for download.

Primary Columns


Retrieval Type

Package type; either "file" or "package". File refers to individual FITS files while package refers to a tar file of various data sets, which can include telemetry, log files or other information. The database table is comprised primarily of values extracted from either FITS keywords (files) or a readme file (both files and packages). Search Fields that are valid for packages have a '(p)' appended to their name.


This is the instrument name for the data you wish to find. Valid instruments to search on are: FGS, MIRI, NIRCAM, NIRISS, NIRSPEC, and TFI. The options are displayed in a searchable menu.

File Name (p)

This box is a blank text box that allows the user to type in all or part of a specific file name to search for. This can be used for both files and packages. A few examples of searches follows. Searching for 'Housekeeping' would bring up a list of packages that contain all of the MIRI Housekeeping files (telemetry) from various test runs. Searching for NRCA1A-SCAalive-Full will find any NIRCAM data with that text string in the filename.

Table of Contents


Test Number (p)

This is a string combining the test campaign and a Job Number from a file. This can be used to search for both files and packages. An example would be icv1_04270 (or  #4270, 04270, _04270, or 4270), which indicates a file taken as part of CV1 testing at Goddard with the JOBID 4270.

Date (p)

Date and time in which the data were acquired. This option also has a histogram with slider bars and date entry boxes that can be used to narrow down a date range. Type the beginning date and the end dates into the boxes and press 'Enter'. Single dates may be specified using the format YYYY-MM-DD hh:mm:ss.

Test Title (p)

Title of test as specified in the test plan or specified by instrument teams. This title comes from the title of the test as defined in the scripts, for example: M03392-DARKS-3270161936_1, G1TRACK-CENTER_1 and NWF03756-CV2-1-4119145426_1. This title is usually (but not always) part of the File Name. To find MIRI telemetry (housekeeping) files, choose 'Package' for Retrieval Type and *Housekeeping* for Test Title.

The options for this search parameter combine Filter and Pupil. The menu below the text box contains all of the available options. The user can type either filter or pupil options into the search box or search the scrollable menu.

For MIRI, there is no pupil, so the filter options are the following: F560W, F770W, F1000W, F1130W, F1280W, F1500W, F1800W, F2100W, F2550W, F2550WR, FND, F1065C, F1140C, F1550C, F2300C, and OPAQUE. If the filter is labeled with a W, it is a wide pass filter, if it ends in C, it is a coronagraphic filter. MIRI also has a neutral density filter (FND) to be used for corongraph target acquisition, and an OPAQUE filter to be used for darks.
