Analysis of the temperature dependence data. The plots on the top are for G i = G 0, the bottom ones are for G i = 1.8 G 0. a Reconstructing the first focusing peak with two Lorentzian peaks at 20 mK. The solid blue line is the experimental data, the green round marker is the fit for peak I, the red square marker is the fit for peak II and the magenta diamond marker highlights the reconstructed focusing peak. b FHWM, γ as a function of temperature: the sub-peaks broaden with increasing temperature in both cases. The markers represent the same meaning as in plot (a). c The polarisation measured with G i = G 0 fluctuates around 0.6 %. On the other hand, the polarisation measured with G i =1.8 G 0 follows an exponential decay
