Multi-loghat fit of the waiting times for the 100 MeV sample, and comparison with results reported in Jorstad et al. (2017). Top panel: joint confidence region for r_burst and τ_burst (for the whole 100 MeV sample, excluding CTA 102). The parameters for the minimum of the Cash estimator are reported with a cross. Contours are reported for 90% and 99% confidence levels. The resolved superluminal features ejection rate and fading time observed at 43 GHz (Jorstad et al. 2017) are reported with a diamond symbol (average values). Bottom panel: r_burst and τ_burst (in black) obtained by fitting the multi-loghat distribution to the data of single sources (for the apparently loudest sources in our gamma-ray sample). For comparison, the apparent ejection rate and fading times for each FSRQs reported in Jorstad et al. (2017) are also reported (in grey).
