The [C/O], [Si/O], [Al/O], and [Fe/O] abundance ratios of the systems that make up our sample (black symbols with error bars) overplotted on the joint probability distributions (blue shaded distributions) of [C/O] and [Si/O] (left) and [Al/O] and [Fe/O] (right) of the best-fit enrichment model. Overall the EMP DLA data are well-described by the inferred enrichment model. Though, there are signs that the DLAs with [Al/O] abundances close to the solar value may be challenging to reproduce.
