Abstract:
We present a clustering analysis of the Texas-Oxford NVSS Structure
(TONS) radio galaxy redshift survey. This complete flux-limited survey
consists of 268 radio galaxies with spectroscopic redshifts in three
separate regions of the sky covering a total of 165°2. By going
to faint radio flux densities (S1.4≥3mJy) but imposing relatively
bright optical limits (E∼R∼19.5), the TONS sample is optimized for
looking at the clustering properties of low-luminosity radio galaxies
in a region of moderate (0≤z≤0.5) redshifts. Description:
Description:
Optical spectra were obtained during the period 2000 October-2003 May
on the 2.6-m Nordic Optical Telescope (NOT) using the Andalucia faint
object spectrograph, the 4.2-m William Herschel telescope (WHT) using
ISIS, the 2.7-m Smith reflector at McDonald with the Imaging Grism
Instrument (IGI), and the Hobby-Eberly Telescope (HET) using the
Marcario low-resolution spectrograph (LRS).

Note (1): Telescopes are designated as follows:
2.7 = 2.7-m Smith reflector at McDonald
HET = Hobby-Eberly Telescope
WHT = 4.2-m William Herschel telescope
Note (2): The positions are that of the radio positions except in
the case of multiple sources where the positions are from APM.
Note (3): In cases where FIRST resolves out multiple components, SFIRST
is the total integrated flux density.
Note (4): Spectra for the TOOT objects will be presented in
Rawlings et al. (in preparation).
Spectra denoted by Benn are from Benn (private communication).
Other redshifts were obtained from the literature.
