Fig. 1

Ideal evolution of $χ_{vis}^{2}$ $\[\chi_{\text {vis }}^{2}\]$ and reduced $χ_{IR}^{2}$ $\[\chi_{\text {IR }}^{2}\]$ as a function of ω_IR. Each blue point corresponds to a different IR weight. This plot is constrained by two asymptotes along the x-axis and the y-axis. These two asymptotes are used to determine a new origin (red point). The best ω_IR value corresponds to the point closest to the new origin.
