Correction this is the SAME bare tube.
but 2 different photo-cells.
Sigh, 5 years...
:-)
So the sentence should read: Both photocells...
Those photocells are not placed at the same spot on the tube
not even symmetrically from one end, and maybe have moved once.

But, as I mentioned in just now in sci.physics,
one could do a FFT on the data to look for seasonal changes.
