Flowchart followed for the reported results on the EWS and EDF. Panel (a) summarizes what has been done for the EWS. In this case, we employed two different approaches: pairing features to labels coming from Phosphoros results at the corresponding depth (paired labels), or with features always from the Wide simulated catalog and labels coming from Phosphoros results at the Calibration and Deep fields depth for the corresponding sources (mixed labels). These pairs of (features, labels) – or (features, posteriors for nnpz (see Sect. 3.4) – are thus given as input for the ML models described in Sect. 3. Panel (b) illustrates the straighter flowchart for the EDF, where the pairs (features, labels) or (features, posteriors) always come from the simulated Deep field.
