Search and Retrieval

HPOL data are contained in the MAST HPOL data base and may be retrieved using the HPOL search form. Users may specify search criteria as well as output format (see search help). On the search results page, click on the Entry ID to view a browse file displaying the ultraviolet spectrum, degree of polarization and position angle of polarization, binned either by wavelength or error estimate. Then mark the datasets of interest to be downloaded as a tar file.

HPOL data files may also be retrieved via anonymous ftp. See Obtaining HPOL Data for information.

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