Abstract:
Integrated magnitudes in U, B, V, R and I bands are calculated for the globular cluseter Omega Centauri. The observed radial chaange in the integrated colour of the cluster shows that the cluster core (r<2') is redder in R - I colour and blure in U - B colour. It is argued that there is an increase in the ratio of AGB stars to the red gaints towards the centre of the cluster.
