Scatter plot of the recovered beam mismatch parameters averaged over time trunks (x-axis) vs. the input values (y-axis) for all 1728 detector pairs of a simulation at 150 GHz. The red solid curves have a slope of 1 and a y-intercept of 0. The red dashed curve has been offset vertically by the mean bias on δp estimated from systematics-free simulations. The correlation coefficient R and the standard deviation of the bias on the deprojection coefficient σ(Δ) are exhibited.
