Abstract: Carbon abundances, especially at low metallicity, reveal the early chemical evolution of a system, tracing the supernovae (SNe) that contributed and how much of their ejecta made it into the next stellar generation. Our sample from the textit{Pristine} Inner Galaxy Survey (PIGS) includes $sim 350$ metal-poor ([Fe/H]~$+0.7$) as in the Galaxy under-predicts the number of CEMP stars in DGs, and for Sgr a cut at [C/Fe]$~sim +0.35$ may be more appropriate, which brings the frequency of CEMP stars in agreement with that in the Galaxy.arXiv:2406.18636v1 Announce Type: new
