In an attempt to improve (?) previous TF data from QUAD 07, today I checked the cabling connections to both chains and added wipes around connectors that were touching the structure/test stand.  I then retook the RO R TF (which showed an unexpected DC offset).  The results showed no improvement and looked identical to the previous round of measurements.

I also swapped an L2 AOSEM that was showing low counts and retook spectra for all stages.

Attached are the spectra for QUAD 07.  L1 and L2 flags are not aligned.
