  The Combined NVSS-FIRST Galaxy (CoNFIG) survey was defined by selecting all
sources with S_1.4GHz > 1.3Jy from the NRAO VLA Sky Survey (NVSS) in the north
field of the Faint Images of the Radio Sky at Twenty-cm (FIRST) survey. We
carried out FRI/FRII morphology classification from NVSS and FIRST survey data;
to complete this process, new 8GHz VLA observations for 31 sources were
obtained at 0.24 arcsec resolution. Optical identifications and redshift
information were compiled for about ~80% of the 270 radio sources in the
sample, the mean redshift being ~0.6. A major goal of this sample is a better
definition of the individual luminosity distributions and source counts for FRI
and FRII sources, in order to determine accurately the evolution of the
luminosity function for both types. Amongst the aims are the issues of whether
the two populations are really distinct, whether physical evolution schemes
permit one type to evolve into the other, whether the dual-population unified
scheme for radio AGN remains viable, and the role radio AGN - star-formation
feedback mechanisms.
