\caption{\label{tab1}The statistics of the studied graben systems. All measurements are in kilometers. (Distance from the center of the nova structure, the widths and lengths of separate graben). Due to the difficulties in deriving exact measurements, the corona-nova 45S/303.5E does not have widths for the graben set in 33$-$65~km.}
