Caption: Figure 2.

Upper: folded PTF light curve of J1250 at the best-fit period, P = 2.92217 days, together with a sine fit. For ease of comparison of the photometric and spectroscopic data, the sine wave shown here uses the best-fit photometric period and amplitude, but the best-fit spectroscopic phase. Lower: residuals from the fit.
