Results from our search for the binary period. Top panel: Periodogram made from the J1650 photometry using ELC. This plot shows the absolute deviation as a function of the trial period, where a smaller value of the absolute deviation indicates a better fit. Bottom panel: Periodogram for J1650 derived from the rest‐frame analysis of the spectra. This plot shows the maximum cross‐correlation value as a function of the trial period, where a higher cross‐correlation value indicates a better fit. Both periodograms have their best statistic at the same trial period, namely ﹩P=0.3205﹩ days (dot‐dashed line). The dotted line denotes the period reported by SF02 (﹩P=0.212﹩ days).
