\caption{Summary of spectral types (SpT) and distances~(${D}_\ast$) derived from our fits for confirmed supergiant stars in our sample. ($^\ast$)~sources with an accurate spectral type found in the literature~($^\dagger$) confirmed supergiant stars whose temperature derived from our fits was used to assess their accurate spectral type. References to the determination of the spectral type and/or spectral class of these sources are found in Table~\ref{tab1}.}\label{tab7}
