public class NonstandardDensityAnalyzer
extends CLIAnalyzer
(For Fig 5) Computes the lowest eigenvalue of the smeared "nonstandard" energy density
defined with the function \(F_P(\theta) = \big((1-\nu) + \nu \cosh\theta \big) F_\mathrm{min}(\theta+i\pi)\).
This is done for the free and for the sinh-Gordon model (\(B=1)\), with \(\nu\) being varied
between given limits.
Takes four command line arguments: the number \(N\) of discretization steps,
the rapidity cutoff \(R\), the maximum value of \(|\nu|\) and the number of steps
to divide this interval in \(\nu\) in.
