  We present preliminary results of the Johnson-Cousins (U)BVRI surface
brightness profile decompositions of the Seyfert galaxies Mrk 79 and NGC 5548.
The profiles were modelled as a sum of a Gaussian law for the nucleus, a Sersic
law for the bulge and an exponent law for the disk. A flat bar was added to the
model profile of Mrk 79. The parameters and the total magnitudes of the
structural components were derived.
