Hubble Space Telescope Call for Proposals for Cycle 17

10.7 Access to Data Products

Data products are stored in the HST Data Archive (see Section 7.2 of the HST Primer). These products can also be archived using 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, either through the MAST Web site or the StarView interface. 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 Web page 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 make that request to archive@stsci.edu. HST data normally become non-proprietary one year after they are taken.

The HST Data Handbook describes the data produced by the instruments. The Space Telescope Science Data Analysis Software (STSDAS) Web Page 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).

• Observers with questions about the retrieval of their data should contact the Archive Hotseat (see Appendix A.1).
• Observers with questions about the analysis and calibration of their data should contact the STScI Help Desk (see Section 1.5).
