I_E image of the Perseus field of view after subtraction of the intra-cluster light (ICL): blue dots indicate the position of each disc galaxy, red dots show the position of ellipticals. Orange lines shows the right ascension and the declination of I_E image. In the background, the method of identification for each galaxy is displayed, with visual markers distinguishing galaxies classified by photometric redshifts (z_phot, square symbols) and spectroscopic redshifts (z_spec, circular symbols). The yellow dot highlights the location of the cluster centre (NGC 1275).
