[Radiance-general] Sun angles,

Hi!

While it may be much better to use empirical weather data, gensky will 
calculate the brightness of the sky dome and the sun from the sun 
position. So while overriding these calculated values using b, B, r or R 
may be the way to improve results for a given location, the value given 
by gensky is not really unspecified. At least I would hope so... ;-)

CU Lars.
