Notes. For each event we show: the event date, the time range of the events in the two channels, the apparent PoS velocity, radial velocity, and, in brackets, Doppler dimming coefficients calculated considering the electron temperatures distributions of Gibson et al. (1999) and Vásquez et al. (2003) extrapolated at the radial position of bright structures, the de-projected residual acceleration, and Carrington coordinates of the eruption directions estimated by the triangulation method as explained in the text.
