Fig. 30


Amplitudes of fast (left panel) and slow (right panel) HCEs. Amplitudes are computed by jointly fitting fast and slow templates. Solid lines correspond to power laws fitted to the tails of distributions (above 1 μK), the high amplitude fast events above 7 μK being removed from the fit; the number of those high amplitude fast events is not compatible with the power-law distribution. Dot-dashed lines are Gaussians fit to the distributions near zero amplitude and are representative of fitting errors. Parameters of the fitted distributions are given in the figure legend. Fast events (and to some extent slow HCEs) have a varying temporal shape from event to event. It appears that the variation can be fit by a contribution from the slow HCE template. This explains in part the negative tail of the distributions of fitted amplitudes. The rest may be confusion between events inducing an anti-correlation of amplitude parameters.
