[Radiance-general] evalglare

[Jan Wienold]

Hi Martin,

oh yes, there seems to be an error in the calculation of the VCP.
I have to admid, that I have used evalglare only for daylight situations 
yet. So I've used only DGI, CGI and DGP yet, although I've implemented 
other indicees, too.
As soon as I return from my ski holidays (in about a week), I'll check that.
