In the code, for a given Expiration, we use different methods to perform the calculations *set-by-step*: 1. Calculate the non aerosol-dependent quantities in the emission rate, which is the multiplication of the diameter-**independent** variables: :meth:`cara.models.InfectedPopulation.emission_rate_per_aerosol_when_present`. This corresponds to the :math:`vl_{in} . BR_{k}` part of the vR(D) equation. -2.
