Weighted average and the 1σ uncertainties of the phase retrievals considering the third and the fifth epoch of the first image.
|Fe II||22.5 ± 2.3 days||22.7 ± 1.9 days||22.7 ± 1.8 days||22.8 ± 1.7 days|
|Hα||21.9 ± 2.0 days||21.9 ± 1.5 days||21.9 ± 1.4 days||21.7 ± 1.3 days|
|Hβ||21.6 ± 2.1 days||21.5 ± 1.8 days||21.5 ± 1.8 days||21.4 ± 1.7 days|
|Fe II + Hα + Hβ||22.0 ± 1.4 days||22.0 ± 1.0 days||22.0 ± 1.0 days||21.9 ± 0.9 days|
Notes. We list the results for the three absorptions lines (Fe II, Hα, and Hβ) for the three different S/N values (10, 20, and 30) and for the noiseless case, indicated by S/N = ∞. The last row shows the values when using all three lines, assuming the noise and the microlensing in these lines are uncorrelated.
