Abstract:
We report the results of a search for hard X-ray binaries (HXRBs)
among previously unidentified sources from ROSAT PSPC pointed
observations, using the automated X-ray source classifier ClassX.

Global Notes:
Note (G1): X-ray brightness is defined by
mxtot=-2.5log(Ctot)
where Ctot is the total count rate in the energy band 0.1-2.0keV
Note (G2): The three hardness parameters, R0, R1, and R2, characterize
a ROSAT X-ray spectrum in the soft, medium, and hard parts of the
ROSAT energy band, respectively, and are defined by:
R0=C(0.4-0.9)/C(0.1-0.4),
R1=C(0.9-2.0)/C(0.4-0.9),
R2=C(1.3-2.4)/C(0.9-1.3),
where C is the count rate in the energy band shown in parentheses (in keV).
