BS, SRM dither lines

[Jenne, Sheila]

We have had dither lines on for the BS and SRM, both pitch and yaw, for the last hour or two while we've been trying to increase the laser power.  This is meant to be reminiscent of the test by Stefan and Elli back in August (alog 20777 and alog 20827), where we can look at how the demod phase in the AS36 signals is changing as a function of laser power.

Sheila may have some transfer function points that she looked at, at different powers, but a more full analysis will come during the daytime.

Lines were put in using the ADS of the ASC.

BS pit 30cts at 5.7Hz

BS yaw 30ct at 6.4Hz

SRM pit 100ct at 6.2Hz

SRM yaw 1,000ct at 6.8Hz
