Confidence regions derived from L_cg, L_svg, and L_vg with x^abd5. The solid and dashed lines represent L_cg in the left panel and L_vg in the right panel, while the colored areas are from L_svg. The black star stands for πⁱⁿ and gray areas represent the non-explored parameter space. The dotted lines are different isolines, the variance Ĉ₅₅ of the bin with highest S/N in the left panel and ln(detĈ) for the right panel. The contour area is reduced by 22% when taking the CDC effect into account. The parameter-dependent determinant term does not contribute significantly.
