Predicted "spurious sinusoidal amplitude" is 7.6 mmag so the measured amplitude of 3.0 ± 1.2 mmag is smaller than expected and therefore porbably not "real."

raw spo Overlaps LC by Curtis, below, but not enough to verify structure in Curtis LC.

Same data as above; expanded mag scale to show sinusoidal fit. ______________________________________________________________________________________________________________________________


raw spo Target label should read "WD2207-303".
