Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

    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.

    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;

              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).
