χ2-surfaces (1σ, 2σ, and 3σ) obtained for G64-12 by varying two line parameters at the time, as indicated on the respective axes; red dashed lines: Nfree = 5 and black solid lines: Nfree = 4. The other free parameters have been optimised at each grid point. The best-fit value and associated error bars are indicated for Nfree = 5 in the top panel and Nfree = 4 in the two lower panels (bullets).
