Description:
A catalogue of 328 positions, redshifts, bJ magnitudes and bJ-rF
colours of galaxies down to bJ=20.5 in 4x0.67 degrees slice close to
the North Galactic Pole is presented. Two additional tables containing
positions, magnitudes, colours and radial velocities for stars and
galaxies not in the main catalogue are also included. The photometry
errors are about 0.2 for magnitudes and 0.3 for the colours. The
radial velocity errors are estimated as being about 70 km/s. The
redshift completeness level of the sample is of the order of ∼35% at
bj=20.

History:
A corrected version, taking into account the Erratum, was kindly
supplied by Christopher Willmer () to Nancy G. Roman
() and to Heinz J. Andernach
(). Table 2 was added at CDS, in catalogue
originally stored as J/ApJS/104/199.
