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.
