Keywords: surveys - stars: low-mass, brown dwarfs - galaxies: evolution -
          infrared: general

Description:
    The survey is a high galactic latitude, large area (552 square arcmin)
    blank-field sample to a 5σ limit of K=17.3mag. Star-galaxy
    discrimination is performed.
    The infrared observations were made over the period 1987-1988, using
    the infrared camera IRCAM at the 3.8m UKIRTelescope at Mauna Kea,
    Hawai. The pixel size is 1.2arcsec.
    The redshift survey (spectro.dat) concerns 124 galaxies of the survey,
    and was carried out on the Anglo-Australian telescope and the William
    Herschel telescope at La Palma over the period 1990-1992, with a
    multi-fibre spectrograph for the brighter objects (R<19), long and
    multi-slit spectrographs for fainter objects.
