Zp versus roll. Zp versus roll for the nucleosomal DNA dataset. The solid vertical line at roll = 1.2° denotes the mean value for roll in free B-DNA, while the two dashed vertical lines at roll = -14.7° and 17.1° denote the values 3σ away from the free B-DNA mean value for roll. The rest of the specifications are as described in the caption for figure 1.
