Phase plots for the 2503867 period calculated using ephemeris 3. Top: a phase plot of all yellow-band photometric observations prewhitened for the 106495 period. Middle: a phase plot of the magnetic field observations from measurements of Neiner et al. (2014) from spectra not affected by technical problems and for the mean values from all lines. The rms errors of the measurements are shown by the error bars. Bottom: a phase plot of the Gaussian-fit He i 6678 Å RVs.
