Fig. 4


Peak frequencies and peak luminosities, separated into low, intermediate, and high states for the synchrotron peak (top row) and high-energy peak (bottom row). While the low and intermediate states follow the blazar sequence for both peaks, the high-energy peak in both states show a peculiar, almost inverted behavior, although the number of sources (especially BL Lacertae objects) is too low for any conclusive evidence. The estimated uncertainty is given in the lower left corner of the left panels for sources with average coverage (orange) and for SEDs with a lack of data near the peak position (gray).
