Notes. Column 3 shows the minimal variability time scale in the GeV band from Vovk & Neronov (2013), Col. 4 the variability time scales derived here. Column 5 lists the SMBH masses estimates selected for the analysis here (numbers in brackets indicate the corresponding reference; please see the discussion in Sect. 3 for the description of the particular MBH choice).
