Left, from top to bottom: low-resolution (R = 30) N band total spectrum and correlated spectra of the Herbig Ae star HD 142527 obtained with MATISSE. The two correlated spectra shown here correspond to increasing baseline lengths (B = 44m and B = 97m). The disk region probed by the different spectra is indicated for each panel. The uncertainties affecting the measured spectra are indicated by the single error bars in the top right-hand corner of each plot.
