Hα vs. Hβ peak velocity for the central (upper), blue (middle), and red (bottom) peak from the month-averaged profiles. The dashed line represents the expected function for an equal peak position in both lines, while the solid line represents the best fit of the measured data. The correlation coefficients are: r = −0.12 (P0 = 0.5) for the central, r = 0.51 (P0 = 0.3E-02) for the blue peak, and r = −0.26 (P0 = 0.15) for the red peak. The parameters of the best fit are given on the plots.
