128 Chapter 4. The cross-identification method
4.3 Conclusions
We have presented a cross-identification method to search for REXBs, which are
potential microquasar sources. The obtained results give confidence to the proposed
method, since the output list of objects included all but one known persistent HMXB
microquasars within |b| < 5 ◦ . The unidentified sources in the list have been divided
in two groups, depending on the offset between the RBSC and NVSS positions.
The Group 1 source list contains 8 objects with offsets smaller than 1σ, while the
Group 2 source list contains 5 objects with offsets between 1 and 2σ.
Finally, since some microquasars could have been ejected from the galactic plane
(Ribó et al. 2002), we are planning to extend this project up to higher galactic
latitudes (5 ◦ < |b| < 10 ◦ ).
