Abstract (EN):
We have observed the central regions of the Coma cluster, both spectroscopically and photometrically, in a field of about 50x25 arcmin(2). Our sample is 95 % complete in redshift up to a magnitude b(26.5)=18.0 - we have doubled the number of galaxies with redshifts members of Coma in this region to a total of 205 - and our photometric data is complete up to V-26.5=22.5. We derive two luminosity functions for galaxies with bright and intermediate magnitudes, respectively, and propose the best fits to them using a Schechter plus a Gauss function and a Schechter function alone.
