Colour-colour diagrams showing star cluster photometry results. Panels a–c: T aperture photometry (blue dots). Panels d–f: C aperture photometry (red dots). Distributions of star cluster models with masses from 102 to 105 M are plotted in the background (grey density contours). Colour indices indicated on the X axis are constructed from T magnitudes in panels a–c and C magnitudes in panels d–f. Arrows in the lower-left corners of the panels indicate the extinction vectors of AV = 1, assuming the standard Milky Way extinction law.
