Explanation of columns:
(1) = dissipation distance in units of $10^{18}$~cm and (in parenthesis) in units of 
$10^{3}$~$R_{\rm S}$;
the (spherical) emitting size is ten times smaller;
(2) = black hole mass in 10$^{9}$ solar masses;
(3) = size of the BLR in units of $10^{15}$~cm;
(4) = power injected in the blob calculated in the comoving frame, in units of 
$10^{45}$~erg~s$^{-1}$; 
(5) = accretion-disk luminosity in units of $10^{45}$~erg~s$^{-1}$ and (in parenthesis) in units of $L_{\rm Edd}$;
(6) = magnetic field in Gauss;
(7) = bulk Lorentz factor at $R_{\rm diss}$;
(8) = viewing angle in degrees;
(9) and (10) = break and maximum random Lorentz factors of the injected electrons;
(11) and (12) = slopes of the injected electron distribution ($Q(\gamma)$) below and above $\gamma_{\rm b}$.
