Cauchy Layer

• Opt. Const. Fit boxes: work similarly to those of standard tabulated layers.
  • The difference is that when neither box is checked, the optical constants are calculated using the Cauchy and exponential absorption functions.
  • When either one box or both boxes are checked, the optical constants are taken from an internally stored list of fitting optical constants.
  • This internal list is started with the functional values the first time a fit is performed.
  • However, after the first fit of the optical constants, this internal list may be different from the functional values.
