Time variations of the equivalent widths of the Hα line and the redshifted enhancement. The black error bars indicate uncertainties of the equivalent width of the Hα line by summing the measurement errors between 6557 and 6572 Å. The blue error bars represent the uncertainties of the equivalent width of the redshifted enhancement as calculated from the fitting errors.
