Balmer series lines Hα, Hβ, and Hγ as seen by GHOST compared with the low-metallicity BOSZ templates. The bottom curve shows Hα after subtraction of the BOSZ template and a two-Gaussian fit to the emission profile. No rotational broadening was applied to the template as these lines are intrinsically broad.
