Search and Retrieval

BEFS data are contained in the MAST BEFS data base and may be retrieved using the BEFS search form. As explained in the search help page, users may specify search criteria and output format. On the search results page, users may mark datasets of interest to be downloaded as a tar file.

A "quick search" of the BEFS catalog may be performed by entering a target name or coordinates in the form labeled BEFS Target Search at the top of the left navigation menu.

Users may also peruse a "catalog" of BEFS data. Click on the Data ID in the table to bring up a preview plot and some associated information. Click on the grating entry to obtain the other files (including the time-tagged spectral-photon data). The user may find it useful to read an overview of the data file types. To save the data to disk, hold down the SHIFT key while clicking on the link. (This should work for most browsers. Others may require you to click the second or third mouse button instead of the first.) The data are all gzipped. Some browsers may unzip the data. The files are all in FITS format.

If you have problems retrieving your data, you can contact the help desk via the link at the bottom of this page.
