The parameter space Hio (the unit square), the sets of θio = 0.05 (the solid curve), θio = 20 with the equal p2-spacing (the circle curve), θio = 10 with the equal u-spacing (the circle-line curve), two lines p1 + p2 = u for u = 0.5 (the dashed line, short) and u = 1 (the dashed line, long). Note θio ∈ [0, +∞), p2 ∈ [0, 1] and u ∈ [0, 2].
