(a) Pitch-angle diffusion coefficients for gyroresonance, ﹩{D}_{\mu \mu ,\mathrm{QLT},{\rm{A}}}﹩ (Alfvén modes), ﹩{D}_{\mu \mu ,\mathrm{QLT},{\rm{s}}}﹩ (pseudo-Alfvén modes), and for resonance-broadened TTD, ﹩{D}_{\mu \mu ,\mathrm{TTD},{\rm{s}}}﹩ (pseudo-Alfvén modes), for TeV CRs. The numerical evaluation of ﹩{D}_{\mu \mu ,\mathrm{TTD},{\rm{s}}}﹩ is derived from the numerical calculation of Equation (A1). Its analytical approximation is taken from Equation (A4). (b) The corresponding ﹩{{\rm{\Gamma }}}_{s,s,\mathrm{TTD}}﹩ with the analytical approximation given by Equation (A5) in comparison with ﹩{{\rm{\Gamma }}}_{t,s}﹩ (Equations (36) and (38)).
