Best stellar model of Jekyll, compared to the models of two local LIRGs with Balmer absorption lines, Mrk 331 and Arp 224, obtained by Brown et al. (2014). All these models use spectra to constrain the strength of the Balmer absorption lines (the spectra are not shown for clarity). the models of the two LIRGs were rescaled to match the continuum level of Jekyll at rest wavelengths between 0.45 and 0.48 μm.
