Scientific paper

It is shown that surface-brightness measurements must be accurate to about 0.1 mag at 1 percent of the visual sky brightness in order to determine the spatial distribution of Population II stars in Sb galaxies with bulge-to-disk ratios like those in NGC 891 and in galaxies of later Hubble type. The observations of van der Kruit and Searle (1981) of the edge-on galaxy NGC 891 are fitted with two different models: a thin disk and a de Vaucouleurs spheroid, and a thin disk plus a thicker disk. The observations are well described by both models. The difficulty of discriminating between various shapes for the light distribution of Population II stars increases with galaxy inclination.
