Descripción
Results are presented of an imaging study of eight Sb-Sc spirals, based
on CCD observations in the B, V, R, I, and Z photometric filters.
Presented are grey scale images, both in individual bands and in color
indices, isophote maps, the parameters of the best fits to the isophotes
(ellipticity and position angle as functions of deprojected radius), and
radial profiles in the passbands. The paper explains how the radial
intensity profiles of these galaxies are naturally divisible into inner
bulge, outer disk, and an intermediate zone, and it is shown how the
color index images can aid in the diagnostics of reddening effects due
to older or more metallic stellar population on the one hand, and dust
on the other. The data are presented with a view to facilitating the
task of dynamically reliable bulge-disk decomposition.
