Hi As always - eliminating environmental influence from the results can be challenging. Even with the parts in a vacuum chamber attached to a heated block, there can still be things that directly relate to the building going from day to night mode or from week day to week end mode.
That said - yes there are periodic influences. Everything I've seen appears to correlate to local time rather than sidereal time. I would admit that it could be a function of back fitting.
