J/A+AS/114/465     ROSAT XUV Pointed Phase Source Catalogue (Kreysing+ 1995)

A ROSAT XUV Pointed Phase Source Catalogue Kreysing H.C., Brunner H., Staubert R. <Astron. Astrophys. Suppl. Ser. 114, 465 (1995)> =1995A&AS..114..465K (SIMBAD/NED BibCode)
ADC_Keywords: X-ray sources Keywords: catalogues - Ultraviolet: stars - X-rays: stars - techniques: photometric Description: We present a catalogue of XUV sources from observations by the Wide Field Camera (WFC) on ROSAT during the pointed phase. The ROSAT WFC is a telescope sensitive in the extreme UV range (17-210eV) which observes in parallel with the ROSAT X-Ray Telescope (XRT). The 5916 pointed observations processed are from the calibration and verification phase in June 1990 and from the period 9 Feb. 1991 to 15 July 1994. The catalogue contains 1022 independent source detections which correspond to 328 individual sources, many of which have been observed repeatedly. Each observation was done with one of four filters S1, S2, P1 and P2. Of the 328 sources 113 are new sources (they are not listed in the "2RE" catalogue) and 274 have been identified with optical counterparts. The catalogue contains coordinates, observed count rates, normalized source count rates and the proposed optical counterpart with its spectral class. File Summary:

Note (1): Two different S1 and S2 filters, S1A, S1B, S2A, and S2B, exist. Each filter has a slightly different transmission profile. In most of the observations the S1A and the S2B filter were used, the exceptions are indicated. Note (2): Count rates for sources with off-axis angles greater than 130' are not reliable. Note (3): The observed source count rate and its 1 sigma uncertainty (vignetting corrections applied), as determined by the maximum likelihood fit. Note (4): Count rates and errors normalized to the detector efficiency at the beginning of the verification phase. Note (5): As found in the WFC Bright Source Catalogue (Pounds et al. 1993), or from SIMBAD. Note (6): The ROSAT Observation Request number can be used for retrieving observations from the online in Tuebingen (Brunner and Kreysing 1993). Note (7): 1: WD, cal, ser; 2: WD, non-cal, ser; 3: WD, cal, target; 4: WD, non-cal, target; 5: not WD, non-cal, target. 'WD' is White Dwarf, 'cal'/'non-cal' means the source was used/not used for the in-flight calibration, 'target'/'ser' means the source was the target of a planned observation or otherwise a serendipitously detected one).
