Position of the sample of candidate Cepheids in the Bailey diagram, now classified as CCs (blue circles) and T2Cs (red squares). In the background, other well-known CCs (light green stars) and T2Cs in the MW (light blue open symbols) are plotted. Literature T2Cs are divided into the three main subtypes described in Fig. 1. The gray diamonds indicate stars whose T_eff values are too low to be Cepheids.
