We presented surface photometry analysis for 50 radio galaxies which complement our previous study of 29 objects from a complete sample of 95 low redshift radio galaxies. Detailed morphological and photometrical properties of the galaxies are reported. As previously found by other studies (e.g., SH89; Ledlow & Owen 1995), we confirm that the galaxies associated with this kind of radio emission have mostly elliptical morphology.
In some cases, however, the galaxy hosting the radio source is found to have a substantial disc component (S0-like). Moreover the surface brightness radial profiles of radio galaxies often exhibit deviations from de Vaucouleurs r1/4 profile, due to the presence of nuclear point sources (likely associated with the active nucleus) and/or to low surface brightness extended halos.
A detailed description of each object is given in the appendix, while a full discussion of the results for the whole observed sample of 79 radio galaxies is presented in Govoni et al. (1999).
