   A better way to distinguish Herbig Ae/Be stars from other objects is
to plot 2MASS colors on color-color diagram (such as H-Ks vs J-H), and
plot a vector to show the direction of the reddening.  If MisV1147
siginficantly deviates (brigter in Ks) from the locations A-B stars and
reddend A-B stars, the color more strongly indicates the Herbig Ae/Be nature.
