LSPE-SWIPE only. Fitted tensor-to-scalar ratio on the mean angular power spectrum over 200 CMB-only simulations, including lensing and different values of the amplitude of the primordial tensor power spectrum. We consider the cases of B-mode maps reconstructed with: the recycling method (RM, red), the iterative recycling method with three iterations (magenta), the inpainting recycling method (orange), and without any E–B leakage contamination (ideal, cyan). The input values of r are represented with vertical dashed grey lines. The used likelihood is shown in Eq. (15) and the covariance is given only by the input CMB signal (ideal case). A binning scheme of Δℓ = 15 is employed and the first three multipoles (ℓ ≤ 4) are excluded. The error bars indicate the bounds at 1σ obtained from the posterior distribution.
