Description

The concept of 'Sequences' of early-type galaxies has been introduced to describe the magnitude Bsub(T) effective radius Asub(e) relation in clusters, according to the definitions and data in the Second Reference Catalogue of Bright Galaxies. For Main Sequence objects, a formula involving the average brightness msub(e) within Asub(e) and the color U-B (or U-V) can be used to estimate relative luminosities and distances of E-SO galaxies

Abstract (French)

Un classement en 'Sequences' des galaxies E-SO a ete introduit pour rendre compte de la relation entre magnitude Bsub(T) et rayon effectif Asub(e) pour les galaxies d'amas, selon les definitions et les donnees du Second Reference Catalogue of Bright Galaxies. Pour les objets de 'Main Sequence', une formule impliquant la brillance moyenne msub(e) dans Asub(e), ainsi que la couleur U-B (ou U-V), peut etre utilisee a l'estimation des luminosites et des distances relatives des galaxies E-SO
