How can I find the new association name for an old dataset?

With the final calibration of STIS data products, the names of old datasets have changed. In some of the cases, single datasets (singletons) have become part of an association. In order to facilitate the search of old data, the following tables provide the mapping of the old dataset names or association names to the new names currently available at the STScI archive as well as new singletons that have been incoroporated into new associations.
