Abstract:
A catalog of extended extragalactic radio sources consisting of 10460
objects is compiled based on the list of radio sources of the FIRST
survey. A total of 2339 objects are identified with galaxies and
quasars of the SDSS survey and the Veron-Veron catalog. The
distribution of position angles of the axes of radio sources from the
catalog is determined, and the probability that this distribution is
equiprobable is shown to be less than 10-7. This result implies that
at Z equal to or smaller than 0.5, the spatial orientation of the axes
of radio sources is anisotropic at a statistically significant level.

corresponding radio component identified by
the program
143-146 F4.1 arcsec Dist ? Distance between the optical object and the
big axis of the radio source
--------------------------------------------------------------------------------
Note (1): If the value of this parameter is equal to unity (1.0) it means
that we could not find either V- or g-band magnitude for the object.
