CMD of only the early-type Virgo sample is shown. The solid red line is constructed by the average measured in successive magnitude bins (1 mag per bin), the dashed black lines denote the CMR for the M_V > −14 mag subsample, M_V < −14 mag respectively. The errorbars shown here do not include the systematic uncertainty of the photometric zeropoint, as this would only cause an equal shift of all data points.
