[Radiance-general] Clarification of Evalglare Output

[Raghuram Kalyanam]

Hi,

I am working with Evalglare for my project. Some of the contents of the outputs are not clear, exactly how they meant. I got the following output

Could some one explain

1. difference between E_vert, Edir and if indirect vertical illuminance which is not shown here could be defined as (E_vert- Edir) ?
2. What are Eglare_cie and Lveil_cie? if you could explain in simple terms it would be good.
3. How is the lum_sources calculated? is it area weighted or just the average of luminance sources?
4.difference between Lveil and Lveil_cie?
5. what is band_avlum? every time i get -99 as its value.
6. Why is the last column for each glare source repeated i.e i think its sigma which is repeated? is it on purpose or its a bug?

If you have some documentation which can explain this, that would be very useful.



Thanks & Regards,
Raghu
