Two examples of pulse profile variations in terms of a combination of ξ_S and φ_C. (A) The pulse profile of the polar cone component in figure 12c in which ξ = 5 and φ_C = 60° changes to the left-hand profile by replacing ξ to 10, and further changes to the right profile by replacing φ_C to 30°. (B) The pulse profile of the polar cone component in figure 12e in which ξ = 5 and φ_C = 60° changes to the left- and right-hand profiles by replacing (ξ, φ_C) to (10, 30°) and further to (10, 15°), respectively.
