Notes. The upper table contains the results of spectroscopic observations of WR 127 obtained in different years. The lower table contains the observational results from which estimates of orbital inclination i and/or mass loss ĖWR rate are derived.
Calculated by us from radial velocity curve for N V by Hiltner (1945).
