Source Lists for the Hubble Legacy Archive (HLA)

摘要

The Hubble Legacy Archive (HLA), a joint project of the Space Telescope Science Institute (STScI), Space Telescope - European Coordinating Facility (ST-ECF) and the Canadian Astronomy Data Centre (CADC), is currently being constructed as a means of providing a higher level of HST archival data to the astronomical community. We are currently in the Early Data I3,elease stage of the project. In this presentation we provide a general examination of the strategy and the steps currently being taken to produce source lists for Advanced Camera for Surveys (ACS) imaging data. We include both IRAF DAOPHOT- (Stetson, 1987) and Source Extractor-based (Bertin & Arnouts 1996) lists to facilitate the needs of the community in the identification of point and extended sources, respectively. These source lists are being created from drizzled-combined, astrometrically corrected ACS images. Future plans include the development of an All-HST-Sky source list that will include observations for the various HST instruments.
