CO line strength plotted against the continuum slope. Positive values indicate deeper CO lines and redder continuum slopes. Spaxels between 0 1 and 0 2 of the center are shown with blue crosses and those within 0 1 with red crosses. The deviation toward redder colors and weaker CO lines is due to emission from hot dust. The slope is measured from the flux ratioed spectra, thus a value of zero indicates the same spectral slope as an A0 star. Errors on the CO depths are ≲0.005 and on the continuum slopes are ≲0.0002.
