[Radiance-general] Sun angles,

Hello Everyone,

I am trying to find illuminance values on an yearly basis, I am 
expecting to get different values for different seasons. Say if we 
compare between march nad december, we should get higher values of 
illuminance for december as compared to march. But I am getting 
almost same values for both the months.

I am not sure if the software is considering sun angles in 
calculations.

I am running this script to find the values,



#!/bin/csh -f

set mon=12
set month=March
set day=21
set coord=(-a 30.00 -o 82.35 -m 84)
rm $month.out
while($day<23)
foreach hr(08 09 10 11 12 13 14 15 16 17)
echo "hr=$hr"
set skypar=($mon $day $hr +i $coord)
echo "$month/$day/$hr">>$month.out
oconv room.rad '\!gensky '"$skypar" sky.rad>hr.oct
mkillum -ab 0 -ad 1024 -av 0.1 0.1 0.1 hr.oct "<" 
windowillum.rad>illumination.rad
oconv -i hr.oct outside.rad Conv-0.rad illumination.rad>hour.oct
rtrace -h -I -ab 1 -ad 4096 -as 128 -av 0 0 0  
hour.oct<mainsamplesupwards.inp|rcalc -e 
'$1=47.4*$1+120*$2+11.6*$3'>>$month.out
#`./newglares.csh hr.oct $month.out`
echo " ">>$month.out
rm hr.oct
end
@ day++
echo "day=$day"
end


Let me know if there is anything wrong with this.

Thank you
