Hemos obtenido las magnitudes aparentes de las estrellas del cúmulo M6 detectadas tomando dos estrellas de referencia, HD 318112 y HD 318118, y promediando las correcciones necesarias para convertir las magnitudes instrumentales en normalizadas. Hemos elegido estas dos componentes porque sus magnitudes publicadas en SIMBAD son medidas y no estimadas, y promediamos para disminuir el error de cálculo.
En la siguiente tabla aparecen reflejadas las magnitudes aparentes publicadas en SIMBAD, las magnitudes instrumentales calculadas a partir de los flujos medidos por la CCD del telescopio LCO y las magnitudes normalizadas tomando como referencia las magnitudes publicadas en SIMBAD para HD 31812 y HD 318118.
