BBSS test stand transfer functions

On May 19th, 2026, we took our first set of transfer functions for the BBSS after swapping in the glass optic. They all came out looking good, albiet very noisy because the suspension wasn't covered.

Comparing them to the last measurement we did in the staging building, the peaks still all match up well. There is just a consistance difference in magnitude, but that is probably just due to the difference in electronics between the QUAD stand in the staging building and the BS electronics in the LVEA.
