In support of HST data calibration, reduction and analysis a number of supporting documents, software tools and auxiliary information bases are maintained at STScI and elsewhere.
| Instrument Handbooks | General information about HST instruments. Instrument information can also be found on the ACS, STIS, NICMOS, WFPC2, FGS, and other instrument web pages. | 
| HST Data Handbook | In depth discussion related to the display, calibration, reduction, and recommended user analysis procedures for each of the archival and currently active HST instruments. | 
| STSDAS | The Space Telescope Data Analysis System (STSDAS) is provided to users wishing to apply modified calibrations to HST data. | 
| Calibration Workshops | Several months after installation of new instruments STScI hosts calibration workshops and publishes the proceedings which contain a wide range of papers of interest to data reduction and analysis. Proceedings are available from 1993, 1995, 1997 (STIS), 2002 and 2005. | 
| Pointing and Jitter | Auxiliary support information on HST pointing, jitter and focus. | 
| ST-ECF | The Space Telescope European Coordinating Facility also provides software related to aspects of calibration and analysis. |
