Masses for single stars are derived from their spectral type and luminosity class. In addition, for double lined binaries with the secondary component not classified, mass_binaries will compute the secondary mass from $m_{\rm 1,2}\sin i^3$. Calibrations are stored in files dwarfs.masses, spec_mass.IV, spec_mass.III, spec_mass.II, spec_mass.I in oyster/starbase.

mass_stars Compute masses for stars in startable.
mass_binaries Compute secondary mass.

Function. Return mass for star with specified spectrum.
