Hou, Goodman, and I have a radial-velocity linear damped oscillator model to capture non-exoplanet near-sinusoidal variability in radial velocity surveys (especially for giant stars). Unfortunately, it doesn't seem to be a good fit to the radial-velocity jitter in our test-case real star. So now we have to see if among the data we have there is any nail on which we can use this hammer.
