Maximum variation in the circumstellar line profiles of the stars with respect to their corresponding mean spectrum. For HD 36546 and HD 42111, the insets in both panels show tiny differences between the circumstellar features. For HD 85905, there is a remarkable feature around 25 km/s, similar to those observed in Beust et al. (1990), making it compatible with the FEB scenario.
