Bailey diagram for the Gaia DR3 SOS RR Lyrae catalog (G. Clementini et al. 2023). It uses the recalculated photometric metallicities from T. Muraveva et al. (2025) and also shows our filtered RRab (purple and red) and RRc (light blue) sample stars. The Oosterhoff separation is indicated by a dashed black line based on E. Luongo et al. (2024). Purple dots mark Oosterhoff I-type RRab stars, while red dots correspond to Oosterhoff II.
