These four tables make up the appendix for the paper: ``XID: Cross-Identifications of ROSAT/Bright Source Catalog Sources with USNO-A2 Optical Point Sources''. The production and meaning of all values in this table are given in that work, and are briefly described here:
Table Content From Sec. N_Obj {tab:98} greater 98\% 3.1 2705 {tab:90} 90< pid< 98 % 3.1 2787 {tab:50} 50< pid< 90 % 3.1 5809 {tab:pair} Optical Pairs pid> 50% 3.2 472 The columns of each table (except Table~\ref{tab:pair}, see below) have the following meanings: column & Heading & Description 1 & 1RXS & The ROSAT/BSC Name for the X-ray source 2 & PSPC c/s ($\sigma$) & RASS/BSC Catalog X-ray countrate, and 1$\sigma$ uncertainty 3 & \pid & calculated fractional probability of unique association between the X-ray and USNO objects 4 & $B_{\rm USNO A2}$ & the \usno\ $B$ magnitude 5 & USNO A2 & the \usno\ source name/position (hhmmss.ss+/-ddmmss.s) 6 & SIMBAD crossID & list of all objects $<$10\arcsec from the \usno\ position 7 & Type & SIMBAD object population 8 & Class & Classification of the SIMBAD object 9 & $B$ : $V$ & SIMBAD $B$ and $V$ magnitudes 10 & Comments & Comment code In Table~\ref{tab:pair}, the magnitudes and \usno\ designations of the two sources are separated by a backslash. Please be aware of the points of caution regarding the ``Optical Pairs'' counterparts. In column 7, the source types are often abbreviated according to the following scheme, which closely follows the source types used by SIMBAD: Abbrev. Meaning Abbrev. Meaning Abbrev. Meaning $*$ Star HiPM* High Proper-motion Star SN SuperNova $**$ Stellar binary HMXB High Mass X-ray Binary Spec. Bin.

Radio source X X-ray source Em. * Emission line star Rot. Var. * Rotationally Variable Star YSO Young Stellar Object Additional lines are given for each SIMBAD object within 10\arcsec\ of the USNO counterpart (20 \arcsec for the optical pairs) . Note that the counterpart for which the \pid\ applies is the \usno\ counterpart; the SIMBAD identifications are listed to provide {\it possible} identifications of this source. The SIMBAD $B$ and $V$ magnitudes provide a point of comparison with the \usno\ $B$ magnitude which may help in identifying the \usno\ object, however the \usno\ $B$ magnitudes are subject to certain systematic errors, and should be viewed with caution. Column 10 holds comment codes of which, at present, there is only one: P=SIMBAD object has been previously identified as this RASS/BSC source. tabA1_98p.tex ------------ Catalog of RASS/BSC -- UNSO Associations, with pid≥98%, and SIMBAD Sources within 10arcsec {tab:98}} 1RXS PSPC c/s (sigma$) pid B_USNO A2 USNO A2 SIMBAD_crossID Type Class $B$ : V$ Comments
