We expand on the work of Weisz et al. 2012 to consider a wider range of SFHs and stellar metallicities, and show that there are large degeneracies in a periodic, top-hat burst model. We argue that all galaxies of a given mass have similar SFHs and we can therefore include the $L_{H\\alpha}$ distributions (subtracting the median trend with stellar mass, referred to as $\\Delta \\text{log}(L_{H\\alpha})$) in our analyses. $\\Delta \\text{log}(L_{H\\alpha","authors_text":"Benjamin D.
