since vR(D) is a diameter-dependent quantity. :math:`E_{c, j}` is calculated using a Monte-Carlo sampling of the BLO distribution given by **Np(D)**, which contains the scaling factor **cn**.
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. Calculate the the diameter-**dependent** variable :meth:`cara.models.InfectedPopulation.aerosols`, which is the result of :math:`E_{c,j}(D) = Np(D) . Vp(D) . (1 ηout(D))` (in mL/(m:math:'^3.µm)).
2. Calculate the the diameter-**dependent** variable :meth:`cara.models.InfectedPopulation.aerosols`, which is the result of :math:`E_{c,j}(D) = Np(D) . Vp(D) . (1 ηout(D))` (in mL/(m\ :sup:`3` \.µm)).
Note that this result is not integrated over the diameters at this stage, thus the units are still *'per aerosol diameter'*.
3. Calculate the full emission rate, which is the multiplication of the two previous methods, and corresponds to **vR(D)**: :meth:`cara.models._PopulationWithVirus.emission_rate_when_present`
Note that the diameter-dependence is kept at this stage. Since other parameters downstream in code are also diameter-dependent, the Monte-Carlo integration over the aerosol sizes is computed at the level of the dose **vD:math:'^{total}'**.
In case one would like to have intermediate results for emission rate, perform the Monte-Carlo integration of :math:`E_{c, j}^{total} and compute :math:`vR^{total} =vl_{in} . E_{c, j}^{total} . BR_k`
