Greg,
Thanks for that. I'm just a little unsure about the orientation of
this "aligned with x-y plane" in the header .. is this absolute (ie. the
project x-y plane) or does it automatically align with the surface it is being
applied to. Sorry if this is a stupid question, it's just I have had trouble
before simulating fritting with mixfunc and different surface orientations.
Cheer,
Richard.

Hi Richard,
Attached is a .cal file which is distributed with the latest version of
Radiance, I believe. It allows you to specify the spacing of a
grating, and it comes up with a reasonable approximation to the angular
transmission.-Greg
