one-mean to zero-mean for regular cable fitting #240

Closed nicholebarry closed 3 years ago

nicholebarry commented 4 years ago

When incorporating Wenyang's auto ratio branch, I needed to change the convention used in removing the polyfit contribution before cable fitting. This didn't properly percolate to the regular cable fitting.

Therefore, we were taking a hyperfine DFT over something that had a mean of 1 instead of a mean of 0. The associated ringing was rendering the cable reflections useless.

One of those cases where essentially a gain = gain - 1 changes the PS significantly....
