EUVE Second Source Catalog
Listed in IVOA Registry (Virtual Observatory)
This is the 2nd Catalog of EUV objects detected by the Extreme Ultraviolet Explorer (EUVE) and published by Bowyer et al. in 1996 (ApJS, 102, 129).
Description
The data include (i) all-sky survey detections from the initial 6-months scanner survey phase, (ii) additional scanner detections made later during specially programmed observations designed to fill in low-exposure sky areas of the initial survey, (iii) sources detected with deep-survey telescope observations along the ecliptic plane, (iv) objects detected by the scanner telescopes during targeted spectroscopy observations, and (v) other observations.
Plausible optical, X-ray, radio, and/or UV identifications are available for about 65% of the EUV sources. The EUVE all-sky survey detections (indicated by detect_mode = EASS in this catalog) comprise 514 detected EUV-emitting objects, the deep-survey detections (indicated by detect_mode = DS in this catalog) comprise 35 detected objects, and the sources detected during other phases of the mission (indicated by detect_mode = OTHER in this database) comprise 188 detected objects.

Notice that 3 deep survey objects were also detected in the all-sky survey. Most of the sources detected in the other phases principally comprise those detected in deep exposures with the scanner telescopes as part of the Right Angle Program through December 24, 1994, or in long exposures with the deep survey instrument. Because these latter objects were observed with a variety of instruments and exposure strategies, the flux limits and detection thresholds vary over a wide range, and the Bowyer et al. reference should be consulted for more details.
Some of the EUV sources have alternative cross-identifications at other wavelengths suggested for them. Notice that, in such cases, we have followed the original catalog and listed separate entries for each alternate identification. For example, the EUV-emitting object EUVE J1147+202 is listed twice, once with the suggested ID of DQ Leo, and a second time with the suggested ID of BD +21 2357.
Thus, there are 801 entries in this database corresponding to 737 unique EUV sources. This is a service provided by NASA HEASARC .
