Assessment |
An object of class Assessment with estimates of FMSY or UMSY and vulnerable biomass in terminal year. |
reps |
The number of stochastic samples of the TAC recommendation. |
MSY_frac |
The fraction of FMSY or UMSY for calculating the TAC (e.g. MSY_frac = 0.75 fishes at 75% of FMSY). |

Miscellaneous arguments. |
