For 94% of the sources visual inspection confirmed the results of the standard processing with respect to existence and position; the remaining 6% were re-analysed and appropriately flagged. At a brightness limit of 0.1cts/s (8,547 sources) the catalogue represents a sky coverage of 92%. Broad band images are available for a subset of the flagged sources from http://wave.xray.mpe.mpg.de/rosat/catalogues/rass-bsc .

1RXS ROSAT All-Sky Survey Catalogue source name number=1 The name includes the '1RXS' acronym, and is based on J2000 position (format JHHMMSS.S+DDMMSS). This name is used in the generation of a link to a broad band image if this image is available (see NewFlag, and Note (3)) See the changes in sources compared to the 1996 version in the "History" section below --- n_1RXS Names modified from previous version --- RAdeg Right ascension (J2000), decimal degrees deg DEdeg Declination (J2000), decimal degrees deg PosErr Total positional error (including 6" systematic error) arcsec ScrFlags screening flags number=2 the flags are 'T' for 'true', 'F' or '_' for 'false'; '.' for not used n (byte 48) nearby sources affecting SASS flux determination p (byte 49) possible problem with position determination e (byte 50) source extended beyond SASS extraction radius d (byte 51) complex diffuse emission pattern m (byte 52) source missed by SASS --- NewFlag 'new data' flags number=3 the flags are 'T' for 'true', 'F' or '_' for 'false'; '.' for not used r (byte 54) source counts and extraction radius recalculated i (byte 55) broad band image available (html link!) v (byte 56) variability flag (not yet filled) .
