Notes.Tobs(1): observed moment of the primary minimum minus 2 450 000.0, derived from a fourth order Fourier fit; Tmid: center of the observational time span minus 2 455 000.0; ΔT: half range of the observational time span; OC#: various observed minus calculated moments of minima, as described in Sect. 2; eOC#: 1σ statistical error of OC#. The calculated epochs of the primary minima are given by C = 2 454 953.949183 + E × 0.4579515, where E is the closest integer cycle number for the given primary minimum. All O–C values resulted from the analysis presented in this paper, except for the values of Vulcan and MLO. For these we adopted the values by Socia et al. (2018). See Sect. 3 and Table 2 for the template selection in computing OC4 and OC5.
See Appendix A for the details of the preparation of each data segment.
