Description:
To construct the MLR, empirical data for 56 stars in 30 low mass
multiple systems, main sequence components of spectral class M0 and
later were collected and processed. We considered only those systems
where the determination of dynamical masses of components is possible,
that is, where masses are derived directly from celestial mechanical
considerations rather than from relations between mass and some
observational parameter.
