Absolute magnitude vs. period for the AC stars in the central field of CraII (black circles; from V20) and in the tails (red circles) in three different bands, g (top), i (middle), and V (bottom). For g and i we overlay the PL relationships for F-mode AC stars from C.-C. Ngeow et al. (2022b) as black solid lines. In the bottom panel, two different PL relationships in the V band for fundamental (solid lines) and first-overtone (dashed lines) AC stars are shown (B. J. Pritzl et al. 2002; V. Ripepi et al. 2014).
