Calculate F_{OFL} using the Tier 4 harvest control rule

Description

Functio to calculate F_{OFL} using the Tier 4 harvest control rule.

Usage

calcFofl(mmb, Bmsy, maxFofl, alpha, beta)

Arguments

mmb	MMB at mating (from calcMMBmating())
Bmsy	value for B_{MSY} (from clcBmsy())
maxFofl	max allowed F_{OFL} (= \gamma M)
alpha	value for the Tier 4 \alpha constant (the x-intercept of the sloping control rule)
beta	value for the Tier 4 \beta constant (the threshold for MMB/B_{MSY} to allow directed fishing)

Details

none.

Value

the value of F_{OFL} given the mmb/Bmsy ratio, using the Tier 4 control rule.
