Photometric redshift distribution. The solid lines represent the weighted redshift PDFs for the three tomographic redshift bins 0.1 < z_B ≤ 0.6, 0.6 < z_B ≤ 1.1, and 1.1 < z_B ≤ 2.0 from the HSC weak lensing catalogue. The light grey histogram shows the weighted distribution of the best point estimates of the photometric redshift for all the HSC sources in the ELAIS-N1 weak-lensing sample. The dark grey histogram shows the redshift distribution of the LoTSS sources using photometric redshift from matched Euclid Deep Field North data.
