How do I make GSOLVER calculate in wavenumber instead of wavelength?
The point here is that a uniformly sampled DE curve in wavenumber space is not uniformly sampled in wavelength space. In order to alter the sampling in wavelength space so that a plot looks uniformly sampled in wavenumber space one needs to set up a Parameter Run file. An example of this ships with GSOLVER (test.prm). This file is a simple listing of the 10 GSOLVER parameters, one set for each loop through the DE calculation. Construct a file that has the wavelength sample points desired. Using this approach, any set of algebraic constraints between the parameters can be constructed. For example a Littrow mount (where wavelength and angle are coupled) is readily applied using the FileRUN feature. (See FileRUN question.
