Normalized angular momentum ﹩j=J/{J}_{{\rm{c}}}﹩ diffusion coefficients as a function of j for two-body (dotted line) and resonant relaxation (RR, dots). The RR diffusion coefficient is calculated using Equation (18), while the two-body relaxation time is calculated from Equation (125) in Bar-Or & Alexander (2016). The sharp drop in the RR diffusion coefficient occurs where the precession frequency of the test star ﹩{\nu }_{{\rm{p}}}(j)﹩ is comparable to the coherence frequency of the system ﹩1/{T}_{{\rm{c}}}(a)﹩ (see Figure 2). We also show the convergence w.r.t. the maximal harmonic number ℓ in black lines, from ℓ = 1 (thickest line) to ℓ = 5 (thinnest line with dots). In this figure, the diffusion coefficients are evaluated at a ≃ 6 Mpc for an isotropic Bahcall–Wolf cusp ﹩f(E)\propto {E}^{1/4}﹩ of solar mass stars around an MBH of ﹩{M}_{\bullet }=4\times {10}^{6}{M}_{\odot }﹩ and a total stellar mass ﹩{M}_{\bullet }﹩ within the radius of influence ﹩{r}_{{\rm{h}}}=2\,\mathrm{pc}﹩, using SCRRPY.
