Distribution of stars in the spectral subtype vs. luminosity class plane according to the results from MKCLASS with quality evaluation better than “good” and including “good.” The number of stars that fell in each small bin is drawn in different gray levels and is also marked as text in the figure. The rows between two luminosity types are those MKCLASS assigns to both types. For instance, the row between II and III are those II–III given by MKCLASS.
