Scientific paper

This study presents deep optical surface photometry in the R-band for the three spiral galaxies NGC 1003, NGC 5533, and NGC 6674. The luminosity profiles, derived by fitting ellipses to the isophotes, are decomposed into bulge and disk contributions using the method proposed by Kent (1986). The intrinsic bulge and disk axis ratios, used in the iterative scheme, are 0.71 and 0.59 for NGC 5533, 0.44 and 0.33 for NGC 1003, and 0.90 and 0.50 for NGC 6674.
