Bottom: airmass-corrected efficiency (no atmospheric absorption) for the MR mode as a function of seeing (image quality IA.FWHM). Top: total photon-detection efficiency for the MR mode in binning 4 × 2 as a function of wavelength. An example of an image quality of IA.FWHM of 0.67″ and airmass of 1.376 is shown.
