quick jitter measurement,

While LLO was down, Cheryl took the interferometer to commisioning at 22:10 UTC do the jitter measurements described in WP 6384  This took about 7 minutes.  

We had not redone a jitter injection since the model rates were increased to 16kHz.  I redid the injections, and got good measurements to about 2kHz where the sensor noise of the IMC WFS limits the measurement.  

The new measurements are included in the attached noise budget plot, which is still missing some noises but has an estimate of the noise from the ITM elliptical baffles based on data that Annamaria and Robert took durring PEM injections in December.
