[HDRI] Re: hdrgen's response curve file

While in general this works, in my case it was not obvious enough - at
least I had to ask :-) Thank you for the explanation.

Now, I see that I get a function for each channel. What I guess is that
the function is sensor response ( picture luminance ), is this
assumption true?

What I actually would like to do is, for a range of picture luminances,
plot a graph of the sensor output using the polynomal as given by
hdrgen, and overlay it with the response curve as written by pfstools. I
am using both tools at the moment and would like to see the differences
for the given range of luminances caused by the different algorithms.

Is this possible at all?

Is there any kind of unit related to the sensor response values?

TIA&CU Lars.
