Frequency evolution of the fitted parameters for OC (lighter circles) and MC (darker circles) models for all LBA sessions. The signal was integrated in time within each session. Top row: B-mode. For most frequencies here the MC and OC measurements coincide within the point markers. Bottom row: Q-mode. Left: the midpoint between components φ_mid(ν). Phase 0 corresponds to frequency-averaged φ_mid for the OC model for each session. Middle: the separation between components φ_sep, fit with a power-law. Right: the FWHM of the components. Black and white markers indicate the FWHM corrected for intra-channel dispersive smearing (see text for details).
