Subject: Floated vs Landed Table Spectrum 

I landed the table today to diagnose our TRANS and REFL power fluctuations and enable easier scattering searches.  (It seems that our TRANS and REFL power fluctuations have ceased, need more time to be sure, but this points to cavity misalignments from slight table motion causing the power fluctuations)

I noticed right away that the spectrum changed, in particular, the scattering shelf extended to even higher frequency.  I made a plot comparing the beatnote from just before landing the table and just after using ~/Git/cit_ctnlab/ctn_labdata/scripts/SeismicAndScatteringStudy.ipynb
Data GPSTimes for Floated Table = 1205884032 to 1205884332
Data GPSTimes for Landed Table = 1205888438 to 1205888738
