Scoring and classification of the S/N and CNN for planets cross-correlated with template channels of CO and H₂O. Overall, 12161 planets containing either CO, H₂O, or both, alongside with other molecules, were inserted with a scaling factor of 8. Left: Aggregated ROC curves as already shown in Fig. 11 from Sect. 4.1. Middle and Right: Amount of planets that can be recovered by the perceptron and the CNN, for different characteristics (i.e. all planets, those containing either CO or H₂O, or both.
