Question:

What is the peak enhancement factor (gamma)? (When using a JONSWAP spectrum)

Answer:

When defining a JONSWAP spectrum, it is possible to adjust the gamma value using an optional third subparameter. The gamma value controls the "sharpness" of the peak of the spectrum and can be used to modify the shape of the spectrum to better match real-world observations. The default value is 3.3.
