Notes. The first two columns list the sector and number of RR Lyrae variables in each sector. The third and fourth columns represent the median values for the frequency drift and the Lyapunov exponent in a given region. The fifth column contains a fraction of RR Lyrae pulsators with regular orbits (based on log₁₀ΔΩ < −1). Columns 6, 7, and 8 list circularity values for different coordinate projections. The subsequent columns list the same parameters, but for red giants.
