Table 2
List of GLEs, in the order of increasing time to maximum, and of parameters of the associated SXR bursts and CMEs. Columns (2) and (3) give the time to maximum and fractional excess measured on GLE profiles without any fit to the light curve. Columns (4) and (5) give the rise time and decay time derived from the fit to the time profile described in Section 4. Columns (6), (7), and (8) give the start time, time to maximum, and peak flux of the SXR burst associated with the GLE. Column (9) gives the position of the active region associated with this SXR burst on the solar disk. Columns (10), (11), and (12) give the time of the first detection, the velocity in the plane of sky and the reconstructed velocity of the associated CME. All times are in UT. The correlation coefficients between the GLE time to maximum and the other parameters are given in the last two lines, with the p-values of the correlation indicated inside brackets. See text for further details.
