Now that stuff is working again, I took a spectrum of the gyro in the newest configuration (the one detailed here).
The calibration is: 6.103 x 10-4 V/ct * 375 kHz/V * (lambda * S)/(4*A) [rad/s / Hz] = 3.09 x 10-4 rad/s /ct
It is roughly a factor of 10 better than before at and below 10 Hz, though this comes with the grain of salt that the calibration was off by a factor of 2*pi before, and that there exists some ambiguity over whether or not the measurement can be trusted due to our incomplete understanding of the loop. The noise above 10 Hz is pretty much the same.
It appears that someone was futzing with the gyro over the week, as the BOOSTs on both boxes were turned OFF and the CW camera was off center. Please document your futzings.
