Near-infrared light-curve distribution of the two regimes. In red we present the first more variable segment and in blue we plot the most stable segment. Gaussian fits of the two distributions give reduced χ² of 1.2 and 4.4 in the quiet and flare part of the light curve with 19 and 29 degrees of freedom, respectively, in accordance with the asymmetry of the flaring part distribution, which is also visible by eye.
