Extract
In two strips of 22° × 1° and 5° × 1° near the SGP Vettolani et al. (1993, IA U Symposium 161, “Astronomy from Wide Field Imaging”, H.T. MacGillivray ed., Reidel, in press) have made a deep redshift survey as an ESO Key Project. All the galaxies down to bJ ≃ 19.4 were observed with the OPTO-PUS multi-fiber spectrograph on the 3.6 m telescope in La Silla, yielding 3348 redshifts. The survey has a typical depth of z = 0.1. It fully samples the optical luminosity function down to B = −15 and various galaxy populations (e.g. normal galaxies, LSBDs and BCDs) are present. Interestingly, emission lines (OII, Hβ, OIII) have been found in a large fraction of the galaxy spectra (≃ 40%), suggesting strong evolution of the galaxy population in terms of enhanced star formation.
