The fraction of the contribution by modelling giants of parameter set 5 in the TRILEGAL model. The upper panel shows the giant counts simulated by set 5 of the TRILEGAL model in the NGP field. The colour code covers the star number density from 1 to 10 per square degree, 1 mag in g, and 0.1 mag in g − r. Lower panel: the relative fraction of giants to all stars in the model. The colour code is from 0% to 40%. (A colour version is available on-line.)
