Dwarf Cosmology with the Stromlo Missing Satellites Survey
Figure 3
A series of four mock colour-magnitude diagrams of a 10 Gyr old, single burst stellar population (Padua library) at 150 kpc with realistic Galactic foreground (TRILEGAL; [64]), background galaxies (ACS; [65]) and photometric errors as expected from observations at an 8-m class telescope. Each stellar population has its total luminosity decreased by one magnitude from left to right. The top of the main sequence and the MSTO remain the only visible features that reveal the presence of an ultrafaint dwarf.
