Caption: Figure 3.

Fourier parameters ϕ₂₁ and ϕ₃₁ as a function of log P for F-mode classical pulsators in the Galaxy (left panels) and LMC (right panels). Blue points represent classical Cepheids, orange points—type II Cepheids, green points—RR Lyr stars, purple points—single-mode anomalous Cepheids. Parameters of the F-mode light curve of OGLE-GAL-ACEP-091 are marked with red triangles.
