I was plotting the color magnitude diagram of a globular cluster and I noticed something odd. On most H-R diagrams, the turn-off from the main sequence to the giant branch is somewhere between (B-V) magnitude values of about .5-1.0. On my plot, the turn-off is between about -.4 and -0.1. I am assuming that there is some data adjustment being done that I have missed. I am also kind of puzzled by the presence of what appear to be a few hot stars, either super-giants or stars that are much hotter than the sun, neither of which should be present in a globular cluster where the stars are about the age of the Milky Way.
