Notes. The table presents the sample size and fraction of noisy SOM cells occupied by the calibration sample, fpix (all, %), along with the fractions of cells representative of the wide sample fgs and spectroscopic number counts Nspec across 10 equi-sized tomographic bins (Wright et al. 2020b). The data reveals a notable scarcity of sources for calibration in bins 1, 7, 8, 9, and 10 compared to the other bins.
