How to get Illuminance (Ev)

about DGP.pdf (995.4 KB) Hello.
I would like to calculate the illuminance (Ev) at the observer’s eye position by the simulation of “Honeybee”. Is it possible?
Ev is a parameter in DGP.

The intent is to decompose the first and second parts of DGP. If the illuminance (Ev) of the observation point is known, DGP can be decomposed into terms.

The fact that DGP can be obtained from simulation means that (Ev) in the formula of DGP can also be obtained.

I would like to know if there is a way to extract only illuminance (Ev) from the simulation results.
