Same as Fig. 6 but for different forecast settings. In this case the confidence contours obtained in this work from the void size function model (light-blue contours with dashed lines) are computed relaxing the constraints given by calibration parameters. The Euclid forecasts derived with void cross-correlation are computed with a model-independent approach, while IST forecasts are computed with the pessimistic setting described (Euclid Collaboration 2020).
