We show ﹩{\rm{\Delta }}{\psi }_{{\rm{lin}}}^{({\rm{golden}})}﹩, the gas-induced dephasing due to the linear torque for the “golden” EMRI in Equation (14), as a function of Eddington ratio (f_Edd), the turbo-viscous coefficient (α), and the disk aspect ratio (h₀) for our radiation-dominated disk profile. For each panel, we increase α vertically from 10^−1.25 to 10^−0.25 and h₀ horizontally from 0.01 to 0.1, while keeping the Eddington ratio constant. The color bar shows the range of Δψ_lin from −10^0.5 to −10^−3.5 rad. For each panel, cells left of the dashed black line have observable linear dephasing due to Δψ_lin > Δψ_crit = 0.16 rad. Similarly, we mark this threshold in the color bar. Since Δψ_lin ∝ ﹩{{\rm{f}}}_{{\rm{Edd}}}^{-1}{\alpha }^{-1}{h}_{0}^{-2}﹩ in Equation (15), the linear dephasing increases with lower f_Edd, α, and h₀.
