Color maps of the optical photometry (left) and EW_Hα (right) from LS I +61 303 as a function of the orbital phase and superorbital cycle. The red crosses and blue stars correspond to the phases of the maxima of the sinusoidal fits to the orbital variability of the optical photometry and EW_Hα, respectively, for the first and second seasons (see Table 3). The dotted color lines represent the orbital phase drift of the emission peaks caused by the superorbital variability for the optical photometry (red), EW_Hα (blue), radio (black), and X-rays (green). The radio and X-ray drifts are taken from Fig. 3 of Chernyakova et al. (2012) using data of the previous superorbital cycle.
