Examples of galaxy likelihood ℒ(z) (dashed red lines) and de-biased posterior distributions (solid black lines). The spec-z (photo-z) are indicated with dotted green (magenta) lines. These galaxies are selected in the tomographic bin 0.4 < z_p < 0.6 for the DES/Euclid (top panels) and LSST/Euclid (bottom panels) configurations. These likelihoods are not a random selection of sources, but illustrate the variety of likelihoods present in the simulations.
