Photometric model of the three main galaxies in the Hydra I cluster core in FORS1 V-band image. Left: observed V-band image calibrated with the zero-point from Arnaboldi et al. (2012). Center: galfitm model including the ten Sérsic components listed in Table 1, obtained with the non-parametric fitting method. Right: residual image (original minus model), normalized by the sigma image that contains the error and noise of the observations.
