Abstract:
The results of V-band CCD photometry for 72 low-luminosity radio
galaxies from the B2 sample is presented. Most of these galaxies are
of early type and their photometric and morphological properties are
studied in the paper. We present the resulting surface brightness
profiles and isophote parameters' profiles, including ellipticity,
position angle, and B4, for 59 galaxies.

should be zero for a perfect ellipse and indicates "boxy isophotes" if
B4 is negative and "disky isophotes" is B4 is positive.
