How do I adjust neph measurements to a different wavelength?
For the neph correction you would so a linear interpolation using the appropriate angstrom exponent. So to correct 550 nm scattering to 530 nm scattering: angstBG=log(scat_450/scat_550)/log(550/450) scat_530=scat_450*(450/530)^angstBG example: If scat_450=20 and scat_550=15 then: angstBG=log(20/15)/log(550/450)=1.44 scat_530=20*(450/530)1.44 = 15.8 To adjust the other two wavelengths you’d want to use the angstrom exponent spanning the range of the adjustment.
