Redshift dependence of the forecast measurements that could be obtained from the 15 000 deg²Euclid survey (purple data points). These are generated from a random realisation of the Euclid CCF (Sect. 5.2) and so the central values can be shifted relative to the Flagship results in Fig. 8. Low redshift measurements from current SDSS data obtained using the same analysis method by Nadathur et al. (2020b) and Woodfinden et al. (2022) are included for comparison.
