Data products are available from the HST Data Archive (see Section 7.2 of the HST Primer). Enhanced products for non-proprietary observations may also be available from the Hubble Legacy Archive (HLA, see
Section 7.3 of the Primer). Any processing or scientific analysis of the data beyond the standard “pipeline” calibrations performed by STScI is the responsibility of the observer.
Observers retrieve their data directly from the Data Archive through the MAST website. In order to retrieve proprietary data from the Archive, proposal PIs and those designated by them must first register as Archive users. This can be done using the
Data Archive Registration website available from the HST mission pages at MAST. PIs should register before their observations are made. PIs wishing to allow others to access their proprietary data should send that request to archive@stsci.edu. HST data normally become non-proprietary one year after they are taken, though this depends on the proposal type (see
Section 8.7).
The HST Data Handbook describes the data produced by the instruments. The
Space Telescope Science Data Analysis Software (STSDAS) Webpage has links to the software used to calibrate and analyze HST data, and to documentation on its use (see also
Section 7.1.1 of the HST Primer).
