Notes. Summary of the eight scenarios of combinations of Euclid and ancillary data considered in this work and the corresponding 2σ magnitude limits that were applied to the photometry. The number of intermediate-z and high-z galaxies that are inserted in our simulations (based on their fiducial redshift) is indicated in the last two columns.
