Аннотация:Brightness and colour distribution profiles have been obtained from observations with the magnetic-focusing image tube for 5 late-type galaxies. Rotation curves and density distribution models have been derived as well. Comparison of photometric and kinematic data shows that the stellar-population content changes slowly with the galactocentric distance. Density depression in the central parts of the disc is needed for explaining the rotation curves of three galaxies out of the five studied.
