Klems_half.cal error

I get the following error using klems_half.cal:

rcontrib: C:\Program Files\Radiance\lib\klems_half.cal, line 32:
rcontrib:               khaccum(7) + khazn(azi,360/khnaz(8))
rcontrib:                                                  ^ bad constant expression

It seems khnaz only has 7 elements. If I remove the line that generates the error, I get the results I expect.

Thanks for spotting this error. I have corrected the HEAD. (Guess I never tested the Klems half basis!)
