The remaining 1512 objects are extragalactic and listed in Table2.
Column 1. ROSAT RBSC name, format 1RXS JHHMMSS.S+DDMMSS.
Column 2. NED Common Name, if available.
Column 3. ROSAT BSC X-ray Flux.
Column 4. NVSS position, unless noted otherwise.
Column 5. NVSS 1.4 GHz Flux density.
Column 6. Identification Probability P(R,V)
(Equation. Identifications with a '-' have been
accepted despite having a low probability.
Column 7. B magnitude from NED, if available;
otherwise from USNO as indicated by '()'. Identifications with a
'-' denote empty fields.
Column 8. Redshift, if known. From NED unless noted otherwise.
Identifications with a '-' represent objects for which
spectra was taken but a redshift could not be determined. We
have obtained optical spectra with
the KPNO 2.1 m telescope for many of the bright identifications
which did not possess published redshifts. The detailed description
of these spectra will be given in a subsequent paper
(Bauer, Thuan, Condon 2000).
Column 9. NED optical morphology, if available.
Column 10. Spectral classification, if known. From NED unless noted otherwise
in redshift column.
------------------------------------------------------------------------
AGN Active galactic nuclei, type unknown
Blazar BL Lacertae type object with variable emission line spectra
BLLAC BL Lacertae type object
BLRG Broad-line radio galaxy
cD Central dominant galaxy, Early-type stellar absorption continuum
Early Early-type stellar absorption continuum
HII Starburst galaxy with narrow emission-line spectra similar
to HII regions
HPQ High polarization QSO
LINER Low ionization narrow emission-line region
LPQ Low polarization QSO
QSO Quasi-stellar object
Sy1-2 Seyfert galaxy, emission-line spectra classified from type 1 to 2

Notes:
O - Optical position given: because identification is more than 3sigma
from radio position or there are multiple optical candidates
R - NVSS position and/or flux density remeasured.
F - High resolution position and flux density taken from the FIRST 1.4 GHz
survey (White et al. 1997).
S - Extended radio emission - central point source and single lobe;
using central point source position and total emission.
E - Extended radio emission.
D - Extended radio emission - double; using centroid and total emission.
T - Extended radio emission - triple; using central source position and
total emission.
1 - Derived from optical spectra obtained with KPNO 2.1m telescope during
1997$-$1999. A dash (-) indicates there is not enough spectral
information to classify
