WebAn absolute magnitude – spectral type H-R diagram is a plot of intrinsic luminosity versus quantized spectral classification (and hence temperature). An apparent magnitude – (B – V) H-R diagram has not removed distance effects, unless it is of a star cluster. Even so, interstellar reddening effects have not been removed from either axis.
