Einstein Catalog HRI Deep Survey
Listed in IVOA Registry (Virtual Observatory)
This database table contains primary HRI source parameters for the 202 HRI sources found in the Einstein Deep Survey.
Description
The Einstein Deep Survey (EDS) program consisted of very deep X-ray exposures in selected regions of the sky at high galactic latitude. The main purposes of the survey are to investigate the nature of the extragalactic X-ray background through direct source counts at very low flux levels and to study the nature of the very faint X-ray sources which comprise a significant fraction, if not all, of the soft X-ray background.
