Similar to the Fig. 30, but limited to pulsating LPVs and distinguishing between sources identified as C-stars (red symbols, bottom panel) or not (blue symbols, top panel) according to Gaia low-resolution spectra (Lebzelter et al. 2023). The numbers of these sources are indicated in the legends. Gray points in the background are O-rich (top panel) or C-rich (bottom panel) LPVs in the LMC from the OGLE-III catalog (sources whose OGLE primary period is flagged as LSP are excluded from the bottom panel). For the LMC, we adopt an average distance modulus µ_LMC = 18.49 mag following de Grijs et al. (2017).
