-There are several aspects to consider when setting up broadband calculations. The FFT result is discrete and the set of wavelengths that are computed depends on the length of the input data. It is also non-linear, the most dense are the high frequencies (short wavelengths). The source itself has some spectral dependence and the result should be corrected for this (the source spectrum is automatically placed in xspectrum.txt file).+There are several aspects to consider when setting up broadband calculations.

 A more detailed tutorial on these aspects will be available in future. A more detailed tutorial on these aspects will be available in future.
