ADC_Keywords: Clusters, galaxy ; Galaxies, photometry Keywords: clusters: Cl 1409+524 (3C 295) - galaxies: evolution - stars: formation Abstract: We observed the cluster Cl 1409+524 (z=0.46) with an imaging Fabry-Perot interferometer. A sequence of Fabry-Perot images (FWHM=1.0-1.3nm) was used to search for redshifted [OII]λ372.7nm- and [OIII]λ500.7nm line emission. We studied 144 galaxies up to a limiting continuum R-band magnitude of 22.5mag within 1 Mpc around the cluster center. Previously known emission-line galaxies in the cluster were confirmed and 17 new members with emission lines were found. Their star formation rate of 1-2M/yr is typical for normal spirals. We have imaged the cluster with broad band B, R and seven intermediate band filters (FWHM=10.0-20.0nm) in order to derive low-resolution spectral energy distributions of cluster galaxies. These were fitted by template spectra to estimate Hubble class and redshifts. Based on this decomposition, we derived a percentage of emission-line galaxies of 40±11%.

Note (1): Missing entries appear where photometry was problematic due to saturation of images, bright neighbouring objects, etc.; Note (2): In case were the {khi}2-minimisation gives a redshift estimate outside the investigated range (0.3<z<0.7) it is indicated by a < and > sing. Note (3): Entries marked with (?) indicate problems caused by very bright stars in the neighborhood of that particular object.
