Summary of periodogram analysis for HIP 113201. Top-left panel: combined V + I-band magnitudes versus HJD (-2457670). Measurements on each night were taken in both the V band and the I band; the average of the two bands is plotted here. Top-middle panel: LS periodogram. The horizontal dotted lines show the 99.9 and 98% confidence levels, whereas the red dotted line shows the spectral window function. Top-right panel: clean periodogram. Bottom panel: light curve phased with the 19.6 d rotation period. Red circles are data points from the first half of the observations; blue circles are data points from the second half of the observations. The red dotted line is a sinusoidal fit to the phased light curve.
