Natural reference score vs. chemical information content. Distribution of per-record natural log-likelihood per constraint, ﹩\mathrm{ln}p({\rm{data}}| {H}_{0})/{n}_{{\rm{used}}}﹩, under the meteorite-trained natural reference model as a function of the number of detected E10 numerator elements ﹩{N}_{{\rm{\det }}}﹩ (E10 ≡ {Al, Cr, Fe, Mg, Mn, Na, Ni, Si, Ti}). (a) Photospheric track (atm). (b) Diffusion-adjusted track (acc_ss). Boxplots summarize the distribution within each ﹩{N}_{{\rm{\det }}}﹩ bin; gray points show individual records. Higher values indicate compositions that are more consistent with the natural meteorite reference.
