Light curve (top) and periodogram (bottom) of HD 29399 from the ASAS-3 data (Pojmański (2002)). Top: Data acquired after 3300 [HJD-2 450 000], the ASAS-3300 dataset (see text). Bottom: Periodogram of the ASAS-3300 dataset. The red vertical line corresponds to the 897.2-day period found in the radial velocities, and the dashed-vertical line to the 765-day period found by Wittenmyer et al. (2017). Horizontal lines, from bottom to top, are the FAP levels at 10%, 1%, and 0.1% respectively.
