[vsnet-campaign-data 52] Re: CT Hya observations by Kis (Dec. 2)

[Lew Cook <lcoo@yahoo.com>]

I combined the Dec. 2 and Dec. 4 data, subtracted the 0.16 mag/day
fading trend from the data and ran the PDM period finding analysis in
AVE for these 2 nights' data. Because of aliasing, I get periods of
either 0.0664 day (95.6 min) or 0.0688 day (99.1 min).
I cannot choose between them on the basis of the periodogram.
In either case, the hump present is somewhat peaked compared to a sinusoid.
