Frequency map showing fundamental frequencies in cylindrical coordinates for prograde RR Lyrae stars in the Galactic bulge dataset. The insets present 2D density maps of the face-on projection (with power-law normalization) of nonchaotic (log ΔΩ < −1.0) orbits in a rotating reference frame for eight selected regions, with high density depicted in blue and low density in red. The insets for each region (marked in the right bottom corner) also contain an estimate of circularity for nonchaotic orbits (bottom left corner) of a given region and the percentage of stars (both with chaotic and periodic orbits) in a given region to the total prograde sample (top left corner). Two significant resonances are identified: the inner Lindblad resonance and the vertical inner Lindblad resonance.
