Statistical results of the fitting process of 8000 model parameter sets based on the SED (left), the radial profiles (middle), and the combination of the two (right). The blue crosses indicate the median factor of all parameter estimations as a function of decreasing ice fraction . For f_param > 1 (< 1) a given parameter is overestimated(underestimated). The dashed red line gives a correct estimation with f_param = 1. The vertical lines denote the range from the 0.16 to 0.84 quantile (i.e., 68% of the values lie within that interval).
