Returns an exponential trawl function with base time t.
TrawlExp(t, rho, max_value = 1, min_value = 0.01)
trawl function peak time.
exponential trawl parameter. Should be positive.
Miximal value of the trawl function (if known). Default 1.
Minimal value accepted for the trawl function. Default is 1e-2.
(Vectorised) Exponential trawl function with peak time t and parameter rho. If this function is evaluated using NA, it yields a list of key components (rho, max time difference, total area of trawl set A).
