Returns a single rowed data frame of the SR parameters:
- alpha
Survival from egg to age tR at low density
- beta
Density-dependence
- Rk
Lifetime spawners per spawner at low density
- phi
Lifetime eggs deposited per recruit at unfished equilibrium
- phiF
Lifetime eggs deposited per recruit at the fished equilibrium
- R0
Age tR recruits at the unfished equilibrium
- R0F
Age tR recruits at the fished equilibrium
- S0
Spawners at the unfished equilibrium
- S0F
Spawners at the fished equilibrium
