I-V (upper panel), K-S (middle panel), and F-T (bottom panel) significance tests applied to the period spectrum of VV 47 to search for a constant period spacing. The periods used here are those provided by Table 3, where we considered a single period at 132.05 s instead of the pair of periods at 131.6 s and 132.5 s. No unambiguous signal of a constant period spacing is evident.
