Sunday Afternoon

21:05 UT Vibration mitigation with Shane and John (HBS On, Telescope at Zenith, Stow pins in, L-N cabinets are off (we think))

OVMS plot: ovms.mode2.20190825_2103.jpg (HBS on, LUCI2 coldheads on, 4 treehouse fans on)
We see lots of harmonics of 1.2 Hz up around 45-65 Hz caused by the LUCI2 coldheads. The particular harmonic at 46.8 Hz seems to be exciting an eigenmode in something (unknown), and this is making of order half of the tip-tilt seem by OVMS in the 4D sampling windows. The other half seems to be from excited swing arm eigenmodes near 13 Hz.

OVMS plot: ovms.mode2.20190825_2118.jpg (HBS on, LUCI2 coldheads on, 4 treehouse fans on)
Each OVMS plot covers 12 minutes, and ends at the UT time in the filename. The integrated PSD plots have red boxes that show the normal 4D sampling windows. Upper plot is the time series, second plot is the PSD, third plot is the integrated PSD for Tilt and Tip respectively. These are plotted from OVMS telemetry by ovms_hdfdirect.py.

Harmonics of 1.2 Hz are gone as expected. There is still some excitation near 13 Hz.
