Efficiency factors as a function of grain size for an amC grain at different wavelengths; left panels: values at ~1.2 μm (J band), right panels: Values at ~3.6 μm (Spitzer [3.6] band). Red line: absorption. Blue line: scattering. Black dashed line: radiative pressure. The top and bottom panels represent the RM and J10 optical data sets, respectively.
