| Abstract: | On the base of Tautenburg UBV-Schmidt plates equidensitometric diameters of galaxies of ROOD and BAUM 's list are given and the ellipticities in the three colours are determined. It was found that there is no difference in the ellipticities depending on the colours, on the average. The percentage of spherical objects (ε = 0.00) was found to 21.5 per cent. The surface brightness for 213 objects in the system V is given. The mean surface brightness is 22.75 mag/□′ with a dispersion of 2.5 mag/□′. It shows only a very slight dependence on the integrated magnitude. |
