Contour maps of WA_H (upper panels) and WA_L (lower panels). The first column indicates outflowing velocity (v_out) vs. hydrogen column density (N_H). The second column indicates v_out vs. ionization parameter (ξ). The third column indicates v_out vs. turbulent velocity (σ_v). The green and orange stars show the best-fit parameters for WA_H and WA_L, respectively. The solid lines in gradient colors from dark to light represent the 68.3% (1σ), 90% (2σ), 95.4% (3σ), 99% (4σ), and 99.99% (5σ) confidence levels.
