Notes. Columns are as follows: event happens at the slit positions of the IRIS spectrograph, type of brightening, duration of each reconnection event (in minutes, first number refers to the EB, second number to the Si IV UV burst, separated by a comma), delay of the UV burst with respect to the EB (in minutes, only for cases where both co-exist), presence of an associated surge, existence of Mg II triplet in emission, existence of Mn I absorption lines superimposed on the blue wing of Mg II k profiles, existence of Ni II absorption lines superimposed on the Si IV 139.4 nm profiles, coronal response in the AIA channels, and brightening in the AIA 170 nm channel.
