The Colour-Absolute Magnitude Relation for E Galaxies in the V and 1.05 Micron Wave Bands
New CM data of early type galaxies indicate the CM effect in UV as well as near IR has the same slope and zero point in all the clusters studied. Hence both UV and IR CM relations could be used to obtain independent distances to E, S0 galaxies. When we compare the color-color data of these galaxies with evolutionary synthesis model colors we find the observed U-V colors are bluer and the UV excess component is related to the metallicity. This UV — metallicity relation is the same in all clusters.
