Description
The catalogue lists 9923 radio sources observed at 408 MHz with the Bologna Northern
Cross Telescope. The catalogue is published in four parts with different limits in declination
and limiting flux as follows:
Part No. Decl. limits Limiting flux
B2.1 3235 +29 18 +34 02 0.2 f.u.
B2.2 3013 +24 02 +29 30 0.25 f.u.
B2.3 3227 +34 02 +40 18 0.25 f.u.
B2.4 448 +21 40 +24 02 0.5 f.u.
The standard errors in positions an fluxes are different for the different parts of the
catalogue and depend on the flux (see references for details).
