Scheme of the complete model used in this study. The input parameters (16 in total) are shown to the left (red). Middle column: flow of the model calculation, and each step in the calculation is explained on the right. We note that the stellar mass M_* is used both in the MIST isochrones and in the ANN calculations. The final SED obtained through this process, together with tree additional parameters that account for potential outlier photometry, is used to estimate the model likelihood (see Sect. 4.2).
