I reran our old PUM DAC noise projection (alog 64475).  

This projection works by changing the state of the coil drivers from 3 (low) to 2 (high) and measuring the excess noise in DARM.
Then, we scale the measured excess PUM DAC noise with the the coil driver analog filters engaged.

The idea is, if the excess noise measured in the high noise state 2 is entirely PUM DAC noise, 
the DAC noise enters the system at the analog conversion point and would be scaled down by whatever analog filters are engaged when switching to the low noise state 3.

From PDF 1, this method of measuring PUM DAC noise appears to yield a factor of 20 lower that what the noisemons tell us (alog 68382 noisemon projection).
It could be that the excess noise is not PUM DAC when we change state, or the noisemon calibration is not right.
I've posted the times of the coil driver switches in the .txt so we could go back and look at what the noisemons are telling us at those times.
