Column 1 - An event number corresponding to the Coordinated Data Analysis Workshop (CDAW) Catalog of the severe geomagnetic storms with Dst <-100 nT (Zhang, J., Richardson, I.G., Webb, D.F., Gopalswamy, N., Huttunen, E., Kasper, J., et al.: 2007a, J. Geophys. Res. 112, A10102; Zhang, J., Richardson, I.G., Webb, D.F., Gopalswamy, N., Huttunen, E., Kasper, J., et al.: 2007b, J. Geophys. Res. 112, A12103.).

Columns 2-6 - Information on the geospace disturbance, including the GMS peak date and time, minimum Dst and peak Ap values, FD magnitude, date and time of the disturbance onset (SC).

Column 7 - Levels GMS identification with their solar sources: labels S1 and "+" correspond to unambiguous identifications; labels S2, S2R, M2, M2R, and "-" correspond to probable identifications. The letter `R' after the S1, S2, M2 codes indicates that the solar source of the given FD was refined by us in comparison with the CDAW Catalog.

Columns 8-11 - Information on the corresponding solar eruptive source: date and time of the eruption determined mainly from the peak time of the soft X-ray flare emission, its GOES class, and the position of the eruption site. In column 10, the label `AR' means that the eruption occurred in and around an AR, while the label `non-AR' indicates events resulting from filament eruptions outside ARs.

Column 12 - The summarized unsigned magnetic flux in dimmings and arcades at the photospheric level (Φ) in units of 10²⁰Mx. In three events marked by the asterisks, the dimming and arcade areas and the corresponding magnetic fluxes were measured by using two to three suitable 195 Å images obtained with the 6-hour interval.

Columns 13, 14 - The GMS onset (ΔT_o) and peak (ΔT_p) transit times, measured from the eruption moment at the Sun (the peak time of an associated soft X-ray burst).
