VII/200             Minislice at the North Galactic Pole. II.    (Willmer+ 1996)

A medium-deep survey of a minislice at the north galactic pole. II. The data Willmer C.N.A., Koo D.C., Ellman N., Kurtz M.J., Szalay A.S. <Astrophys. J. Suppl. Ser. 104, 199 + Erratum Vol. 107, 823 (1996)> =1996ApJS..104..199W
ADC_Keywords: Galaxies, photometry; Galactic pole, north; Redshifts Keywords: cosmology: observations - galaxies: distances and redshifts - galaxies: photometry surveys 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. File Summary:
