The TexOx-1000 redshift survey of radio sources I: the TOOT00 region
  We present optical spectroscopy, near-infrared (mostly K-band) and radio
(151-MHz and 1.4-GHz) imaging of the first complete region (TOOT00) of the
TexOx-1000 (TOOT) redshift survey of radio sources. The 0.0015-sr (~ 5 deg^2)
TOOT00 region is selected from pointed observations of the Cambridge
Low-Frequency Survey Telescope at 151 MHz at a flux density limit of ~= 100
mJy, ~ 5-times fainter than the 7C Redshift Survey (7CRS), and contains 47
radio sources. We have obtained 40 spectroscopic redshifts (~ 85%
completeness). Adding redshifts estimated for the 7 other cases yields a median
redshift z_med ~ 1.25. We find a significant population of objects with
FRI-like radio structures at radio luminosities above both the low-redshift
FRI/II break and the break in the radio luminosity function. The redshift
distribution and sub-populations of TOOT00 are broadly consistent with
extrapolations from the 7CRS/6CE/3CRR datasets underlying the SKADS Simulated
Skies Semi-Empirical Extragalactic Database, S^3-SEX.
