Compute Emergent Adults for trivial (L Component)

The number of emerging adults is a function $$\mathrm{\Lambda }S(t)T(t)$$ where

• $\mathrm{\Lambda }$ or Lambda is the mean number of adult female mosquitoes emerging per day

• $S(t)$ or F_season is a seasonal signal (ideally, with an average annual mean of 1)

• $T(t)$ or F_trend is a function returning a trend (ideally, with an average value of 1)
