2σ contours derived for one single source redshift at z = 0.91 and the survey setup presented in Sect. 4. The constraints are obtained by applying the starlet Peak counts (yellow contours) computed on noisy maps filtered using a starlet kernel of [9.33, 18.70, 37.38] arcmin together and the wavelet pass-band filter for the C_ℓ statistics (grey contours) as described in Sect. 4. The dashed black lines are located at the fiducial parameter values.
