Key figures from the paper:
The i-band magnitude distribution of the matched spectroscopic and weak lensing catalogues
The redshift distribution of the validation sample from spectroscopy compared to the 4 photoz codes and COSMOS photozs
The redshift distribution in each of the 3 tomographic redshift bins for different samples (3 different spectroscopic samples - upper 3 rows) and on the DES data itself (bottom row)
The predicted impact of photometric redshift estimation differences on the cosmic shear two-point function and cosmology
