Notes. See Equation (6) for a definition of the model parameters. The numbering scheme for the x_{H i,ı} coefficients is: (1) low-velocity, i.e., local gas, (2) and (3) IVCs and HVCs.

Asymmetric error bands are computed using Minos when the best-fit value is at the boundary imposed during the likelihood optimization process.
