Light Curves
raw spo
raw spo
Same data as above LC, but with systematics removed (provided by Curtis).
raw spo
Same data as above, with expanded mag scale showing unconvincing sinusoidal variation.
raw Roland Santallo must have chosen some red reference stars to use with this blue WD to account for the strong air mass curvature.
raw spo Can you see a small amplitude sinusoidal variation? See the expanded LC, below.
Note: This sinusoidal fit is statistically significant at the 5.6-sigma level.
