Attached are some plots from an updated noise budget, with several measurements retaken in the last couple of days. 

Last time we posted a noise budget 44840 we were missing an intensity noise measurement, here you can see that intensity noise is making a significant contribution about a few kHz. The second attached screenshot shows the intensity noise injection, which only goes up to 3kHz.  This could be contributing to OMC length noise observed here: 44874

PRC2Y gain reduction

The third attachment shows the ASC noise contributions to DARM, only the PRC2 P+Y measurements have been updated since the last noise budget here. Since PRC2Y was previously dominating the ASC noises, I reduced its gain by a factor of 2 and engaged an 8Hz elliptic low pass, now PRC2Y is not showing up in the plot because it is more than a factor fo 10 below DARM.  

Other notes on the noise budget:  

I also reran the HAM3 injections as well as MICH and SRCL today, those curves are updated in the plot.  

I am still using a guess and check method for the optical gain and cavity pole since we don't have the kappas yet.  This time we are using kappa c = 92% and a cavity pole of 440 Hz.
