Wavelength dependency of the DPF used by ICNNA. The kDPF is only known between 740 and 915 nm (as far as the authors know). The values outside the range reported by Essenpreis et al.³² are available from the fOSA software and attributed to Mark Cope (source unknown according to fOSA). Beyond those values, an arbitrary $\mathrm{kDPF}=1$ is applied.
