Notes. The period, P, was determined from an initial fit including only the OVRO data in the range 57779 < MJD < 60053. The joint fit including OVRO and the three ALMA light curves kept the period fixed at this best-fitting value. The fit uncertainties do not account for systematics due to superimposed, shorter term variations (see Appendix C.1). The reference time for the phase, in MJD, is t0 = 59 000. The phase shift, Δϕ0, is defined in Eq. 2.
