Define robust tomographic bins and n(z) via a SOM. Open choices: calibration anchor (DESI vs CFHTLenS); equipopulated vs a-priori bin boundaries; per-bin SOMs vs one master SOM (to avoid dense low-z regions dominating the topology). Cross-check against WZ clustering-redshifts (Romain has code). Owner: Klara.
