The '''Space Telescope Science Data Analysis System''' (STSDAS) is an [[IRAF]]-based suite of astronomical software intended primarily for processing data from the [[Hubble Space Telescope]]. STSDAS is produced by [[Space Telescope Science Institute]] (STScI).

In 2018, STScI stopped support of IRAF and STSDAS<ref>{{Cite web |title=9.4 STSDAS, STSCI_PYTHON and Astropy - HST User Documentation |url=https://hst-docs.stsci.edu/wfc3dhb/chapter-9-wfc3-data-analysis/9-4-stsdas-stsci_python-and-astropy |access-date=2024-04-11 |website=hst-docs.stsci.edu}}</ref> and suggested migrating to [[Astropy]].<ref>{{Cite web |title=Removing the Institute's Dependence on IRAF (You can do it too!) |url=https://www.stsci.edu/contents/newsletters/2018-volume-35-issue-03/removing-the-institutes-dependence-on-iraf-you-can-do-it-too |access-date=2024-04-11 |website=STScI |language=en}}</ref> For the support of the [[Gemini Observatory|Gemini]] IRAF legacy pipeline, selected tasks of STSDAS are still maintained by [[NOIRLab]] in the '''st4gem''' package.<ref>{{Citation |last1=Fitzpatrick |first1=Michael |title=Modernizing IRAF to Support Gemini Data Reduction |date=2024-01-03 |arxiv=2401.01982 |last2=Placco |first2=Vinicius |last3=Bolton |first3=Adam |last4=Merino |first4=Brian |last5=Ridgway |first5=Susan |last6=Stanghellini |first6=Letizia}}</ref>
