5.9-μm band properties. Fitted characteristics of the 5.9-μm band in Obs. 18 (leading side, first three rows) and Obs. 27 (trailing side, last three rows), for the three models described in the text: observed band depth relative to total continuum, band depth corrected for thermal contribution (i.e., relative to model solar reflected component), band position (offset from 5.90 μm), and band FWHM width. The last column shows the correlation between the observed (black) and corrected (red) band depths with the observed 8.25 μm T_B. Spearman correlation coefficients and number of standard deviations significance are indicated as insets.
