Abstract:
This paper focuses on a comparison of the space densities of
Fanaroff-Riley type I (FR I) and FR II sources at different epochs,
with a particular focus on FR I sources.
First, we present the concluding steps in constructing the Combined
NVSS-FIRST Galaxies (CoNFIG) catalogue, including new Very Large Array
observations, optical identifications and redshift estimates. The
final catalogue consists of 859 sources over four samples (CoNFIG-1,
-2, -3 and -4 with flux density limits of S1.4GHz=1.3, 0.8, 0.2 and
0.05Jy, respectively). It is 95.7 per cent complete in radio
morphology classification and 74.3 per cent of the sources have
redshift data.
Combining CoNFIG with complementary samples, the distribution and
evolution of FR I and FR II sources are investigated. We find that FR
I sources undergo mild evolution and that, at the same radio
luminosity, FR I and FR II sources show similar space density
enhancements in various redshift ranges, possibly implying a common
evolution.
Description:
The CoNFIG catalogue consists of four samples, CoNFIG-1, -2, -3 and
-4, which include all sources selected from the NRAO-VLA Sky Survey
(NVSS) catalogue with S1.4GHz≥1.3, 0.8, 0.2 and 0.05Jy respectively
in defined areas.

Note (2): Flag as follows:
w = Wide Angle Tail source
c = possible core-jet source
Note (4): Redshift type as follows:
S = spectroscopic redshift
P = SDSS photoz2 photometric redshift
K = 2MASS Ks-z estimate
I = SDSS i-z estimate
Z = SDSS z-z estimate
R = SDSS r-z estimate
G = SDSS g-z estimate
Note (5): o denotes sources for which the identification was found in
another catalog than SDSS or 2MASS.
Note (6): For No 233 of config1, in original file, Declination contains the
Right ascension value !! so there is only optical counterpart
Right ascension in the table.

Global notes:
Note (G1): Morphological types as follows:
C = Compact sources
C* = Confirmed compact sources from the VLBA calibrator list
S* = Confirmed compact sources which show a steep (α≪-0.6)
spectral index. These are probably CSS sources.
I = FR I type sources
II = FR II type sources
U = sources with uncertain morphology
