Notes. Effective interplanetary length (AU) traveled by protons. Column 1: label of the GLEs. Column 2: length computed from the onset times and the maximum energy of ERNE channels – without the NM point. Column 3: as Col. 2 but with the NM point. The error bars of Cols. 2 and 3 correspond to the standard deviation of the linear fit, increased by the error on the determination of the onset time (owing to background fluctuations). Column 4: length from Reames (2009).
