[Radiance-general] subtended sun angle in gensky and gendaylit

[John Mardaljevic]

Hi Jan,

I followed your discussion in the first e-mail.  Reading it did  
remind me of the (sort of) related issue which I came across a while  
back and always meant to share with this group, but never got round  
to doing so before.  Hence my contribution.

As this thread has been broadened somewhat (or slightly hijacked):  
Christoph - do you set a direct normal threshold in DAYSIM as  
suggested by Francesco?

lower
