Noise-equivalent change in radiance for sampling noise in a double-sided interferogram.
The formula for the noise-equivalent change in radiance (NEdN) for sampling noise [Appl. Opt. 38, 139 (1999)] can work well when applied to the double-sided interferograms of radiance spectra dominated by isolated emission lines, but it does not work well when applied to broad, slowly varying radiance spectra such as a Planck blackbody curve. The modified formula for the sampling-noise NEdN works well when applied to the double-sided interferograms of both types of radiance spectra.
