Comparison between the impact of extinction A_V and distance modulus μ on cluster detectability, for clusters with a mass below 800 M . The blue curve shows f_detected as a function of distance modulus μ for simulated clusters with negligible extinction (A_V < 0.5), while the orange curve shows f_detected as a function of A_V for the nearest clusters in this study (2 < d [kpc] < 3). A correction of 11.5 (the distance modulus corresponding to a distance of 2 kpc) was subtracted from the distance modulus to make its value in this study start at zero, and hence be easily comparable with A_V, which also has a minimum value of zero in this work. The black curve shows f_detected for μ and A_V summed for all simulated clusters. Poisson uncertainties are shown on the bins.
