In an attempt to understand why LLO's kappa calculations are all working nicely, but ours are not, I started looking at the differences between their line demodulation and ours.

First, a change that we are keeping:  When looking at these, I found that the local oscillator for Pcal line 2's demodulation had an amplitude of 0, so I'm not sure what it was actually demodulating.  The LO wasn't anything other than digital zeros.  Sadly, fixing this didn't fix our kappas.  Not so surprising, since this is the line for the kappa_c, which is the one kappa that (somehow, even with this problem) was getting the right answer.

A set of changes that we've already reverted: At LLO, they use singain and cosgain values of 1 for their local oscillator demodulators, whereas here at LHO we use values that match those of our actual oscillators.  That doesn't seem to have any effect on our kappa calculations (which was surprising actually - why didn't the output values change if the demod outputs were different by, in some cases, several orders of magnitude?).  Anyhow, all of these were reverted.

We were out of Observation for a few minutes for this test.

I'm still confused why our kappa calculations aren't working - everything seems like it should be fine.
