Selection of stars in a domain of spectral type

It is also possible to select the stars in a range of spectral types with the command mk and the option -i

mk ts -i "earlier type" "later type"

As is the case for the other selections with the options -p and -g, only the spectral type is taken into account, and not the luminosity class.

Example:

mk ts -i B8 A2 lists the stars with spectral types between B8 and A2.
