Theoretical contour plots for two-shock experiments of equal duration but different temperatures (left column). The b-values represented as discrete weights placed on a grid (right column). The orientation of the constant levels curves (A) and (B) depends on the shocks' duration. The contours for D1 = D2 = 15 minutes are rotated anticlockwise with respect to the contours for D1 = D2 = 20 minutes, (C). Each diamond in (D) and (E) represents a weight proportional with the b-value corresponding to the experimental condition to which the diamond is attached. For each figure, the arrow represents the direction of one principal axis, the other principal axis being perpendicular to it. The anticlockwise rotation predicted by the theory is confirmed by the experimental angle, (F).
