Fig. 2.
Cylindrical projection of the area from which we draw simulated quasars, in ecliptic coordinates, consistent with the ERS coverage defined in Scaramella et al. (in prep.). Euclid/Pan-STARRS sources are drawn from the red area with δ > 30°, and Euclid/LSST sources from the blue area with δ < 30°. The sample with no ground-based counterpart is drawn from the combined area.
