Distribution of source duty cycle (i and ii) as well as source-averaged average rise and fall times (iii and iv), global amplitude (v and vi), and average local brightening and decaying amplitudes (vii and viii) of prominent BBHOP flares against synchrotron peak frequency. Pink crosses and solid markings refer to FSRQs (Q); blue dots and dotted markings refer to BLLs (B). Kendall’s τ correlation coefficient and significance are reported for FSRQs and BLLs. In panel i we show zero duty cycle data, whereas in the other panels we do not. The running averages in the top row (shown as solid lines for FSRQs and dotted lines for BLLs) and the box plots in bottom row are both only calculated for at least ten nonzero values within each bin. In the top panels we show all data points, while in the bottom panels we zoom in on the boxes.
