Jeff and I noticed that today's lock may have some elevated Bounce and roll modes.
9.7Hz bounce modes.
13.7- 13.9 hz roll modes.
Some fundemantal 500 hz Violin modes for fun.
Another plot from 6-600 hz from ealier in this lock.


I also took a look at a different lock ~ 10 days ago pre power outage.
9 hz bounce mode
13 hz roll mode
Some exquisite looking Violins.
