float coeff_perez [] is from Perez's paper in solar energy vol. 50, No.3. pp235-245, 1993.
i would like to adjust A3, A4, A5, A6 and A7 using measurement irradiance data over a whole year for every minute or hour, and update these coefficients under the file perezlum.cal. It means i may need to re-compile gendaylit.exe, which i have no idea how to do it.
i found radiance has another version on gendaymtx.c v2.13. it includes static const double PerezCoeff[8][20]. I am wondering which version of gendaymtx does ladybug GenCumulativeSkyMtx use.
Thanks for your suggestions on honeybee plugin. I will take a look and see how.
Cheers,

However if you tell me more about the project and what you are trying to do maybe I can suggest something else. This component is not perfect in many ways and causes a lot of lagging, at least in my system. …
the drawings/3DPDF/3D data/virtual reality/etc available. Why? because drawings/data are "occasionally" ...er... a bit optimistic (or borrowed from another "similar" project).
Meaning: A4 and a pencil beats any computer hands down.…
