I am covering production for a couple of nights just so you all can see
what is going on.
It is 8 PM here in Batavia, and last night's run just completed.
I have the threshold for detection set at 3 sigma above the noise. This
gets lots of noise hits, but our requirement that there be a hit in the V
and the I camera will get rid of most of them.
Here is the result from last night:
Camera .ast total .cal total
TOM1 832931 141923
TOM2 691788 122394
TOM3 491874 84032
So we got 348349 V,I measurement pairs.
The three sigma threshold seems go dig more real faint mag pairs out of the
noise. TOM3 is low because we lose some frames from noise pick up on the
unshielded cable. I will eventually try another shielded cable. TOM2 is a
little low because it was showing ice crystals on the early frames so I
heated it up and discarded the early frames.
I think this is about par for a summer night's run.
