α value-dependence of the relative velocity change in the deep zone. The black and gray curves represent values evaluated in periods 1 and 2, respectively. Broken curves represent the ranges of the corresponding error bars. The area with a white background represents a range of α values evaluated using the decreased (α = 0.75) and increased (α = 0.82) reference velocity structures
