Spatial variations in the spectrum along the major and minor axes of the disk. Left: continuum flux of HH 48 NE at 4 µm on a logarithmic scale. The colored squares mark the regions used to extract the spectra in corresponding colors in the middle and right panel. Middle: three spectra extracted along the major axis of the disk at radial distances of −70, 0 and 70 au with respect to the center. Right: three spectra extracted along the minor axis of the disk at heights of −25, 50 and 80 au with respect to the dark lane.
