ADS demodulation gain is turned off when the camera servo is used

Jenne, Camilla, Naoki

The ADS error signals are the demodulated DARM control signals at dither frequency, which are not 0 even without the ADS lines. Since people sometimes get confused, we modified the camera guardian so that the ADS demodulation gain is turned off and the ADS error signals get 0 when the camera servo is used.
