(b) for peakness 1 = 3.3 and the cosine angular energy distribution with n f3 = 2
The non-linear energy transfer function has been changed more significantly (see Fig. 4.7b). Now it occupies not only the left-hand, but almost
the entire right-hand semi-plane {a, ,8}. The shape of the isolines resembles
a medusa, being turned vertically counterclockwise. The "medusa tentacles"
