Do we know what the low-frequency peaks are?

George-Hookway commented 1 day ago

I've removed an erroneous peak at ~2100 microHz.

Could this be another case of a binary, with a smaller envelope at lower frequency?

nielsenmb commented 1 day ago

Considering the proximity in frequency to the main envelope, I think I would expect to see the slanted ridges in the echelle if they were equally spaced, similar to what we saw for Merry and Pippin.

That said, the secondary set of peaks are in prime mixed mode territory.

Right, so because their numaxs are so similar, they would have a similar dnu, which would mean it should still be visible on the echelle plot
