Abstract:
Following the study presented in our previous paper, based on the
Nordic Optical Telescope (NOT) sample, which consists of five clusters
of galaxies within the redshift range 0.18≤z≤0.25 imaged in the
central 0.5-2Mpc in very good seeing conditions, we have studied the
quantitative morphology of their bright galaxy population.
We analyzed the surface brightness profiles of the galaxy population
in those clusters, after performing simulations in order to check the
reliability of the fits. We also derived a quantitative morphological
classification.
