HST Data File Names
The links in the table below lead to separate pages containing information about the extensions and file ids associated with every HST dataset. The letters in brackets are used as the first letter of the dataset names for that instrument. Since the calibration system in use produce a variety of files and their nomenclature is not necessarily standard across all instruments, we encourage you to consult the table below for a precise description of each files delivered by the HST archive system at ESAC. For further details please consult the HST Data Handbook.
Furthermore advanced science products from the Hubble Legacy Archive, observation logfiles, quality control files and the previews have their own nomenclature.
