Abstract

From PDS scans of the late-type spiral galaxies NGC 1313, 1365, 6946, and 7793, we determine the surface brightness distributions. These distributions enable us to calculate physical parameters such as Re*, μe, α-1D/B, C21, and M/L. The values of some of these parameters were also compiled from other studies, and all were compared with morphological type T. One of the meaningful results shows that there is a certain correlation between D/B and T, which is constant until T<-1 or 2, and then increases sharply for T>-1 or 2. This may support the validity of the intrinsic formation theory.
