WidzPeak=PDFwidth/zPeak, where zPeak is the highest peak of the (smoothed) PDF

This parameter efficiently picks out low-z faint galaxies that are misclassified at high z, due to their poor representativity in the training sample.
They can be kicked out, or their zcnn can be replaced by zPeak (or something better, yet to be defined).
