I 'll let Pete comment on that one.

Well , it was very straightforward, and we didn't
get very many of them, mainly because WE! wound up
in drifting flight .
We took the measurements as
advertised, except there is one little ~:litch in the
thing.
They wanted you to take a light measurement
out, the, window, and they wanted you to c.o it in
either the heads- up, or heads- down.
In doing thi s ,
that said the horizon was in front of ycu.
Now the
light meter reading looking at the black sky just
above the horizon in the daytime , which was the
total sky, was usually a number around 11. 5.
But
looking at the earth, or just below the horizon, the
meter reading was about 15. 6.
So, I al ways recorded
two readings , the reading for the horizon and the
black sky, because I didn't really know which one
you wanted. With the spot meter the thing just turned
out that way.
Okay, we made one at 01+23+10.
