I still do not follow what you mean. If you look at the three lines
above, you have sza = 45.0D.
Then you execute the following 2 procedure calls:
IDL> int_LUT, wave, nwave, 0.0D, 0.0D, 0.0D, chl[i], foq0
the next call you have shown is:
IDL> int_LUT, wave, nwave, sza[i], vza[i], dphi[i], chl[i], foq
In the first case, the 3rd parameter is 0.0D.
In the second case, the 3rd parameter is sza[0] = 45.0D.
Anyways, I assume what you actually are doing is something
different than what is shown in the messages you posted.
Why not reduce this problem to a very short example, and
post the code here so we can take a look at it.
Cheers,
bob
