Notes. The second and third columns present the literature-based spectral classification and reference sources, respectively. The fourth column details the updated SpT obtained in this work. The fifth column gives the projected rotational velocity from iacob-broad. The sixth and seventh columns list the diagnostic line and the spectral resolution of the spectrum used in the computation.
