Examples for the three cases c = 0,0.5,1 (from top to bottom) of Eq. (A.1) with the added noise with the StudentT distribution (ν = 2.1) and for three levels of noise (standard deviation σ_n = 0.1,0.5,1from left to right column). In each panel N = 60 points are selected with a different random seed. The blue straight line is the least-squares fit to the simulated points (in black). The correlation coefficients and the slope of the fitted straight line are written at the top of the panels.
