N and S are equivalent to M.

Temperatures of Ia0 and Ib are equivalent to Ia.
Temperatures of II is equivalent to III.
Temperatures of IV and VI are equivalent to V.
Color was derived from Mitchell Charity's work on star colors. Each designated color is defined with at least one field (R, G, or B) at full saturation (value equals 255). Actual color values for display would be attenuated across all color components based on the star's apparent magnitude in a given situation.
Mass was derived from many sources including Astrophysical Formulae by Kenneth R. Lang. Many rows are heavily interpolated from known data on star mass.
