Abstract:
A new sample of radio sources, with the designated name CENSORS
(A Combined EIS-NVSS Survey Of Radio Sources), has been defined by
combining the National Radio Astronomy Observatory Very Large Array
Sky Survey (NVSS) at 1.4GHz with the ESO Imaging Survey (EIS) Patch D,
a 3x2deg2 region of sky centred at RA = 09 51 36.0, DE = -21 00 00
(J2000). New radio observations of 199 NVSS radio sources with NVSS
flux densities S1.4GHz>7.8mJy are presented, and are compared with
the EIS I-band imaging observations which reach a depth of I∼23;
optical identifications are obtained for over two-thirds of the ∼150
confirmed radio sources within the EIS field.

Note (1): Morphology code as follows:
D = Double
E = Extended diffuse
M = Multiple
S = Single
T = Triple
Note (2): Radio source position:
For extended sources, this is the location of the radio core, where
one is unambiguously detected, or the flux-weighted mean position of
the radio emission where no clear core exists.

Note (1): The EIS optical counterparts of the radio sources were
identified by maximum likelihood analysis on unresolved radio sources
or those with unambiguous radio cores (class 1, likelihood L>1 for for
inclusion), maximum likelihood analysis on extended sources (class 2,
L>0.3 for inclusion), or inclusion because the optical counterpart lay
directly on top of one of the radio components which could plausibly
be a radio core (class 3).

History:
* 22-Jan-2004: From electronic version of the journal
* 23-Oct-2009: tableb1 corrected (version at CDS was apparently in error)
* 30-Aug-2012: units of Drad / Drad2 were corrected (from "arcmin" to
"arcsec"; thanks to Heinz Andernach, and a comparison with the NVSS).
