These are the target descriptions currently in the HST Archive, indicating which instruments have observations of the given description. Target descriptions are selected by the proposer, and were not always translated consistently. As a consequence, searches on target description should be done with some caution, using wildcards and multiple choices (for example, *QSO*,*QUASAR*).
