Notes. We predicted the fluxes for these emission lines using the relations presented in Sect. 3.2. The rightmost column lists the ratios presented by Hummer & Storey (1987) and Osterbrock (1989) between the fluxes of the Balmer and Paschen lines and flux of the Hβ line assuming typical H II region gas conditions with electron density ne = 102 cm−3, electron temperature Te = 104 K, and case B recombination.
