Ratio of the stellar masses derived from the SED modelling and the true stellar masses in the simulation as a function of the difference between the optical V-band dust attenuation recovered in the SED modelling and in the simulation. Dotted lines indicate agreement between these masses and attenuations. Large symbols with error bars represent the medians in the A_V difference bins. All points are colour-coded by the dust attenuation in the simulations (colour bar). These plots indicate that for all models except the C10 (tau) model, discrepancies between the true and recovered A_V values are not the primary cause of inaccurate stellar mass recovery.
