Hi Eric,
I just found it interesting—it may not be that interesting to other folks.
I would guess that the long exposure scale comes from the extreme humidity
used. This is the longest exposure scale I have plotted thus far for a PT/PD
curve and I found the shape of the curve also to be interesting.
The exposure source was a NUARC.
Best Wishes,
Mark Nelson
