\caption{\label{table1}The most recent terrestrial impact crater data obtained  in August~11th, 2008 from \textit{The Earth Impact Database}. The combined simultaneous pairs of impacts are marked with ``\pari''. The following information of these craters is given: name (Col.~1), location (Col.~2), age and its error  (Col.~3: $[t_{{i}} \pm \sigma_{{i}}]={\rm My}$), diameter (Col.~4: $[D_{{i}}]={\rm km}$) and the crater belongs (``Yes'') or does not belong (``No'') to the sub-sample $C_2$ or $C_3$ (Cols.~5 and~6). The value of $k_{{i}}$ is the cycle number in $C_2$ and $C_3$ (Cols.~7 and~8).}
