Light curve of the combined data of ZGP-BLAP-08 corrected for period changes and phased with the period of P₁ = 1/f₁ = 0.0244008189 d for the two intervals of the rotational phase, ϕ_rot, between −0.05 and 0.2 (green dots), that is, near the minimum of amplitude in Fig. 10 and between 0.4 and 0.65 (orange dots), that is, near the maximum of amplitude in Fig. 10. The two ranges are marked with similar colours in the right panels of Fig. 10. The magnitudes were calculated in 0.05 phase intervals. Phase 0.0 corresponds to BJD_TDB 2459200.0.
