ABSTRACT
The basic components which compose the global structure of galaxies are the halo, bulge, bar, lens, disk, and ring. Some peculiar features such as a box-shaped bulge, warping of the disk and a thin layer of strong absorption are observed best in edge-on galaxies. NGC 5866 is a lenticular galaxy with a dominant bulge and is an object suitable for the investigation of bulge structure. Care is taken in the model fitting procedures to avoid the effects of internal absorption. By this model fitting we have derived the model parameters for several edge-on galaxies of various morphological types. Using the model parameters we can produce a hypothetical profile of each component and of the galaxy which would be observed if the galaxy were to be seen face-on. The dominance of the bulge relative to the disk in the face-on profile varies systematically along the sequence of morphological types.
