[HDRI] Re: hdrgen's response curve file

[Gregory J. Ward]

That's correct, Lars.  I like to keep my file formats as obvious as  
possible.  The first integer is merely the maximum degree of the  
equation, which should be 4 in this case.  It can be as low as 2 and  
as high as 5 out of hdrgen.

The first line is for the red channel response, the second is green,  
and the third is blue.
