Best fit for Si III λ4567 (left) and λ4574 (right) lines from mode identification with the MM for the SC1 RADIAL scenario with i = 60°, υ_e sin i = 100 km s⁻¹, f = 5.25 d⁻¹, and υ_amp = 21 km s⁻¹ as inputs. The data are phase-folded according to the detected frequency. The observational data along with their error bars are shown in blue and the fit in red for the first (top) and second (bottom) moments of the time series.
