Appendix A: Line fitting

thumbnail Fig. A.1

Line profile fitting for the 11 523 (top), 12 028 (middle), and 11 579 datasets (bottom). For display purposes, only the strongest lines from I Zw 18 (component 1, also indicated by the vertical dotted lines), from the Milky Way (component 2), and from the high-velocity cloud (component 3) are labeled. The thin green line shows the individual line profiles. The solid thick red line shows the fit to the data while the dotted red line shows the line profiles assuming the H i region abundances are equal to the H ii region abundances.
