These are from 12/15, Saturday night, during a all-night SN night, working on the equator.
This is all from a sequence. I wonder about the oscillation period, which is 10 seconds.
What mechanical system oscillates with a 10 second period? Strange.
These are selected as all guider plots with any point more than +- 3 pixels from 0.
Blue is x motion, red is y motion.
See Guider Plots 2 for the data and interpretation of the plots in
the night summary for 12/16.
