a Colormap of IPC as a function of the waveplate angle (x axis) and the excitation wavelength (left axis). The gray scale in the colormap represents IPC, and the solid lines (right axis) show individual IPC profiles at equispaced wavelengths between 720 and 840 nm. For clarity, the base level of these profiles has been shifted vertically in steps of 0.5 nA. b I0 (blue, right axis) and C (red, left axis) parameters, obtained from least-square fitting of Eq. 1 to the data shown in a, as a function of the excitation wavelength.
