Uses the formula
$$r(w, t) = r(t) = r_0 \exp{\left(-\dfrac{(t-\lfloor{t}\rfloor-t_0)^2}{2\sigma^2}\right)}$$
where parameters \(r_0, \sigma\) and \(t_0\) are given by new columns
sr_r0, sr_sigma and sr_t0 in the species parameter data frame.
Because mizer measures time in years, \(t-\lfloor t \rfloor\) gives the time
within the year and so \(r(t)\) is a periodic function with
the period of one year.
