The results from today's diagnostic breadboard scan.

The relative power noise measurement doesn't look too bad.  Better than the reference measurement at low frequencies below about 20 Hz but worse elsewhere but not by much.  The first loop power stabilisation servo performance is better than the reference signal at frequencies below about 40 Hz but worse for frequencies above about 1 kHz.

The frequency noise measurement is out of whack.  It is known that perhaps the gains on the servo are not adjusted to their correct values.  Currently the common gain is set to 27 dB and the fast gain to 17 dB.  This will have to be tuned up when time permits.

The beam pointing measurement looks good, or at least okay.

The mode scan looks almost identical to last week.  The percentage higher order mode content is fractionally lower this week but not significant I think.
