a1, b1: comparison of number density of protons np (black, solid), positron number densities ne+ (without annihilation, blue, dotted), and with both production and annihilation rates (green, dashed). a2, b2: comparison of emissivities of the total radiative cooling Qtot and emissivities due to annihilation of pairs Qann. For two sets of accretion disc parameters, (a1, a2) = 1.0, β = 0.2 and (b) = 1.5, β = 0.15. The other parameters are βd = 0.013, E = 1.001, λ = 2.61 and MBH = 10 M.
