Second Extreme Ultra-Violet Explorer Catalog

The payload contains three EUV scanning telescopes equipped with imaging detectors as well as a Deep Survey Spectrometer instrument which divides the light from a fourth telescope between an imaging detector and three EUV spectrometers. There are three source tables in this catalogue: - table1 lists count rates and positions of 514 objects detected during the all-sky survey. - table2 lists 35 sources detected by the deep survey of half the ecliptic plane; three deep survey objects are also detected in the all sky survey. - table3 lists 188 sources that have been detected in other ways, principally by deep exposures with the scanner telescopes as part of the Right Angle Program or by long exposures with the deep survey instrument; table3 includes right angle detections through December 24, 1994.

Because the objects listed in table3 have been derived with a variety of instruments and exposure strategies, the flux limits and detection thresholds vary over a wide range; interested readers should consult the reference listed. Each table has an associated list of identified sources, id1, id2 and id3 (one EUVE source may by associated to 0, one or more counterparts); in nearly all cases they lie within 1 arcmin of the actual source position.
