Table 2:

Structures with 13 or more pairs for which the helical axis is best described by a single-kink line and the alternative double-kink model has a short central segment with 0 or 1 base pairs. In this case the difference in the goodness-of-fit values between the best and the next best models is not used as a classification criterion. Because of the small number of structures different listings are not given.

Number of structures: 9
