Caption: Figure 5.

Left panel: folded light curve for the main pulsation period P₁ = 0.269 days with sine fit (gray) centered on peak (upper curves). Below: residuals of sine fit, displayed at 25,000. Right panel: phase fold to P₂ = 0.17 days. Note the changed horizontal axis and sine fit (gray) with much smaller variation, about 2% of P₁.
