Spawning output-at-age

Calculates spawning output per recruit at age and year using length-based maturity and fecundity scaling.

Usage

get_phi(log_psi, length_m50, length_m95, length_mu_ysa, length_sd_a, dl_yal)

Arguments

log_psi

Scalar fecundity scaling exponent.

length_m50

Length at 50% maturity.

length_m95

Length at 95% maturity.

length_mu_ysa

3D array year, season, age of expected length-at-age.

length_sd_a

Vector of length standard deviations at age.

dl_yal

a 3D array by year, age, length_bin of length distribution weights.

Value

Matrix year + 1, age of normalized spawning output-at-age.
