Notes. The averages were determined for colours of (g − i) > 0mag to avoid extremely blue BCDs, which could be contaminated by strong nebular emission. σ corresponds to the standard deviation of the mean. The label “dE” refers to all early-type dwarfs. For the division of the ETGs into giants and dwarfs the VCC was used.
