Another prewhitening. Many of the modes are starting to show their 12 day rotational sidelobes. Note that f5 seems to be a doublet now, and what look like 1/d aliases remain after prewhitening.... glad I'm not the PI....

Latest prewhitening - the noise continues to go down with new data from SAAO, Tenerife, McDonald, and SSO.
The f6-3xOmega is now
at f6-2.9xOmega.
And the f5+ mode remains!

Here's the latst through 21:00 1 December. F2, F3, F4, and F5 are all triplets now (the F5+omega is in the residuals). BUT! Check out f6 - there's something at f6=3xomega, and that fits perfectly in the pattern of large spacings...

Now resolved a bunch of triplets, and the new frequency, f6, seems to be split by 4 x the rotation frequency!

We're now cleanly resolving the rotatonal sidelobes of f2 and f4, and beginning to cleanly separate f3. f5 may soon become a triplet, and even f6 is starting to show some structure!. Of course, f1 is a singlet - why, Margarida?
Through 01:00 29 November: 15 peaks removed!

15 peaks can be reomved now. F2, F3, and F4 each show both rotational sidelobes, and f5 and f7 are each doublets split by the rotation period (about). F1 and F6 are singlets...

Removed 7 primary frequencies, along with rotational sidelobes of:
f2 (2), f3 (1), f4(2) and f5(1)... we need less noise for the others!
