Color-magnitude diagrams of globular clusters usually exhibit a prominent horizontal branch (HB) and may also show features such as the red giant branch (RGB) bump and the asymptotic giant branch (AGB) bump. Stellar evolution theory predicts that the luminosities of these features will depend on the metallicity and age of the cluster. We calculate theoretical lines of 2-12 Gyr constant age RGB bumps and AGB bumps in the ΔV-[Fe/H] diagram, which shows the brightness difference between the bump…
