Histograms representing the distribution of the RAT Γ_RAT (left) and angular velocity ω_RAT (right) for SC BA grains of different sizes and the AGN as the radiation source. The continuous lines show the mean for each distribution, and the dotted lines show the value calculated using the canonical parameterization (LH07). The mean values for ω_RAT are calculated from the mean values of Γ_RAT shown in the lower panel as well as averages for τ_drag and I_max. We note that the RATs by the canonical parameterization are consistently higher than the mean values of the dust aggregates.
