Top panel: detection percentages for 500 M_⊙ clusters of different ages for grid-element radii from 90″ to 40″. A general increase in detection rates with decreasing radius is noticeable. A decrease in detection rates with increasing cluster age is evident as well. Bottom panel: detection percentages for clusters of four different masses across the age range from 1 Myr to 1 Gyr for the 40″ radius. A decrease in sensitivity for older ages and lower masses is apparent. Clusters more massive than 500 M_⊙ show high detection rates for young ages.
