Reporting Problems

Hubble Observation Problem Reports (HOPRs) provide a mechanism for you to inform the STScI when a problem has occurred with the implementation, scheduling, execution, or data processing of your observations. It is also the means by which the Principal Investigator (PI) makes the request for failed observations to be repeated.

Retrieving Data

MAST is the primary archive and distribution center for HST data, distributing science, calibration, and engineering data to HST users and the astronomical community at large. Over 100 000 observations of more than 20 000 targets are available for retrieval from the Archive.

Data Analysis

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.
