Note: OCLI performed tests on a witness piece at 77 K and calculated the values for the filters themselves. They did not give the filter values for the long CH4 filters. I have calculated those from the witness piece under the assumption that the wavelength shift between the witness pieces and the filters was the same for both runs.
All values given in nm.
