BBSS Bouce measurement results (without BRDs)

Ibrahim, Oli

We ran a long overnight Bounce measurement on the BBSS. The BRDs weren't installed for this measurement. AOSEM flags were not installed, and we were 100g heavier at M1 than we are now (this measurements was taken before 90294). 

With those settings in mind, our measurements show that our Bounce mode was at 19.80Hz. The last time these measurements were taken, back in the staging building (88141), the bounce mode with no BRDs was ~19.74Hz, so they're consistant.

The measurement file can be found in  /ligo/svncommon/SusSVN/sus/trunk/BBSS/H1/BS/Common/Data/ 2026-05-19_2200_H1SUSBS_M1M2_BounceNoBRD_V_0p001to40Hz.xml as r13012.
