Surface Brighteness Distribrtion of NGC 7755

Abstract

Isophote map and luminosity profile of the barred spiral galaxy NGC 7755 are obtained from PDS scanning of PAL 0-471 plate. From the isophote map, NGC 7755 can be classified SBbc(r) with asymmetric bar ring. We get several physical parameters (MTo U(R)CB, U(R)CD, D/B, Cij, M/L) of NGC 7755 from the analysis of the luminosity distribution.
