(1) PGMW # ID (Parker et al. 1992); (2) effective temperature (T⋆); (3) surface gravity (log g); (4) bolometric luminosity (L⋆); (5) mass-loss rate (log Ṁ); (6) terminal wind velocity (r∞); (7) stellar radius (R*) obtained from L* and T*, via the Stefan-Boltzmann law; (8) stellar mass (M*); log of the number of ionizing photons per second for (9) hydrogen (QH); (10) He I (QHe I); and (11) He II models (QHe II), considering X-rays; (12) mechanical luminosity (
); proper units in L⊙(= 3.826 × 1033 erg s–1) are obtained by dividing the result from the Lmec equation by v∞/2c, following the analytical derivation; (13) log of the modified wind momentum (Dmom [M⊙ yr–1 km s–1 R⊙–0.5]), defined as
