Detailed Description

Computes Kmax according to Wathelet et al. (2008)

Todo:

Do not inherit TheoreticalLinearFK but rather use a pointer

TheoreticalFK is used for peak search. TheoreticalLinearFK to find the intersection with level line at 0.5 around found peak (fixing azimuth).

  // Disregard any peak with amplitude lower than 0.1
  // Even if we are interested in peaks exceeding 0.5, the coarse grid search has
  // a step of kmin/4, hence first peak estimates might be less than 0.5 even if peak is
  // above 0.5.
  setNoiseLevel(0.1);
  // Doing this forces us to takeFunction() in destructor
