Notes. Column 1 lists the identifiers of the comparison area (cf. blue numbers in Fig. 1); Cols. 2 and 3 list the time and baseline of the two measurements “A” and “B” that are compared; the ratios of the correlated flux spectra, the total flux spectra and the visibilities, averaged over the entire N-band, are given in Cols. 4–6 respectively. The ratio of the more recent measurement “B” over the earlier measurement “A” is calculated. Measurements which disagree by more than 1σ are highlighted in yellow, those that disagree by more than 2σ are highlighted in orange. If there is a change in the spectral shape, this is indicated by a “b” (more recent measurement is bluer) or “r” (more recent measurement is redder) after the corresponding value.
