Results of the multivariate linear regression models for Θ. Left panel: comparison between Θ and ν sin i. The colours encode T_eff, while the symbol sizes scale with spectroscopic luminosity. The red circles show the predicted Θ value from the best multivariate regression model in Eq. (5) for our LMC sample. The red vertical line in the corner indicates a typical error bar for the predicted Θ values and applies to all three panels. Middle panel: comparison between observed Θ and predictor T_eff, where Θ predicted from Eq. (5) is colour coded in red. Right panel: comparison of Θ predicted from Eq. (5) and the measured values of Θ.
