ADC_Keywords: X-ray sources ; Extreme UV sources Mission_Name: EUVE Description: The Extreme Ultraviolet Explorer satellite was launched on June 7, 1992 from Cape Canaveral, Florida on a Delta II rocket. 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. The 534 objects in the "faint" part were detected jointly in the EUVE and in the ROSAT X-Ray Telescope 0.25keV band (50Å). This joint selection criterion permits use of a low count rate threshold in each survey, roughly 60% of the threshold used in the EUVE all-sky surveys, and 166 of the objects listed in the "faint" part are new EUV sources, appearing in neither the Second EUVE Source Catalog (tables 1 to 3) nor the ROSAT Wide Field Camera Second Catalog (J/MNRAS/274/1165) See also: J/ApJS/93/569 : First EUVE source catalogue (Bowyer+, 1994) J/AJ/107/751 : EUV Explorer bright sources list (Malina+, 1994) J/MNRAS/260/77 : ROSAT Wide Field Camera EUV Bright Sources (Pounds+ 1993) J/MNRAS/274/1165 : The 2RE Source Catalogue (Pye+ 1995) http://archive.stsci.edu/euve/ : EUVE Archive at STScI File Summary:

Note (1): the `Q' column indicates our level of confidence in each source detection: Q=1 denotes likely identification on basis of known EUV emitter from previous work or from membership in a class of known EUV emitters. Q=2 denotes acceptable positional coincidence but little or no other supporting evidence. Q=U denotes some of the detected source counts originate from the known UV leak of one or more of the EUVE filters Q=H means no counterpart has been found, but the detection is statistically secure found, the detection is statistically secure in the sense of its satisfying the more stringent selection criteria. Q= (a blank) indicates that the detection lies in the less stringent group, and no other supporting evidence is available.

Note (1): this flag is set when the source is also present in tables 1 to 3, but with a slightly different name, like the first source EUVE J0003+436 which is named EUVE J0003+435 in table1.dat Note (2): the statuses are: N = newly reported object (not in tables 1-3) 2 = object in 2EUVE (in tables 1-3) W = object in ROSAT Wide Field Camera (J/MNRAS/274/1165) U = a bright early-type star s closer than 1.5' of the EUV position, some or all of the EUVE count rate could be due to UV radiation.
