Notes. Column (1): number of the possible flare. Column (2): date. Columns (3) and (5): pure AGN blue (at 5100Å) and red (at 6200Å) continuum flux, corrected for the host-galaxy contribution, in units of 10-16 erg cm-2 s-1 Å-1. Columns (4) and (6): flare amplitude in %. Columns (7) and (9): Hβ and Hα fluxes corrected for the host-galaxy contribution, in units of 10-14erg cm-2 s-1. Columns (8) and (10): The change in the line flux in %.
