Surface photometry of barred spiral galaxies

Detailed surface photometry has been made for six early-type barred spiral galaxies using high-resolution photographic plates. Azimuthal luminosity profiles are extracted and analyzed in detail. Radial luminosity profiles of the bars and underlying disk components are studied, and the bar components...

Zusammenfassung:	Detailed surface photometry has been made for six early-type barred spiral galaxies using high-resolution photographic plates. Azimuthal luminosity profiles are extracted and analyzed in detail. Radial luminosity profiles of the bars and underlying disk components are studied, and the bar components are extracted and their structure studied in detail. The observed properties are compared with results of numerical simulations of a stellar disk. 66 refs.
