Radiation analysis with Honeybee

I am using Honeybee’s component ‘Run Daylight Simulation’ to calculate radiation on a grid. It works great, but I would like to have a better understanding about the how this radiation is calculated. If I am not wrong, the calculation is done through Radiance, but I am a bit lost with all the information provided in the Radiance website. Could someone point me to the right direction? Is there some some material that explains how the algorithm works?
Thanks a lot!

Check the study folder. There should be a batch file which can review to see all the inputs and outputs.
