Finished another dataset today and this interesting variable turned up! (The x-axis is in days and and the y-axes is in magnitudes).
The white points are the data and the red line is a fit to the 20 strongest frequencies in the fourier transform.
The the "blips" that occur every 5 and bit days is the interesting part! There is also a significant frequency at 3 c/d that has an amplitude of about 500 part per million (yeap,, you heard that right) which gives it a S/N greater than 5 in fourier space.

Another star to put on my "What is the stellar type?" list.

I personally like to reduce datasets blindly. So I don't introduce any personal bias, but I always hate the 1-2 day wait to get the HD number and see what this baby is!
