Parameter dependence of optomechanical swapping rate and total loss rate. Optomechanical swapping rate, J a, and total loss rate, Γ b, are measured as a function of detuning ($\overline{\Delta }$/2π). The dashed lines are two parameter fits based on Equations (2) and (3). For clarity the higher power measurements of Γ are vertically offset by 2 and 4 Hz as indicated by the dotted lines. c J and Γ are measured as a function of input power at a detuning of 1.87 MHz (indicated by black dotted line in a and b). The dashed lines are two parameter fits based on Equations (2) and (3). The ratio between the measured optical power and the input power P _in and the mean bare mechanical dissipation rate (γ ₁ + γ ₂)/2 are the fitting parameters (Methods section). Statistical uncertainties are smaller than the point size
