v denotes a variable star (denota una estrella variable) (average magnitude) (magnitud promedio).

Class is the Spectral Class of the star (es la Clase Espectral de la estrella), denoting its color and surface temperature (denota su color y temperatura de superficie).
The numbers (Los números) (0-9) denote subdivitions of the Spectral Class (denotan subdiviciones de la Clase Espectral). [A9 is next to B0] ([A9 está junto a B0])

Const. is the abbreviated name of the constellation (es el nombre abreviado de la constelación).

Dist. (ly) is the distance in light-years to the star (es la distancia en años-luz a la estrella).
