Time-integrated squared Fourier coefficients that express the power in each term of the expansion for the equatorial plasma density, ρ(t, ϕ), and mass accretion rate per solid angle, f_M(t, ϕ), integrated over the entire time interval from t = 32 191 t_g to t = 32 360 t_g. For the main flux-eruption event analyzed in the text, the integral corresponding to the m = 2 azimuthal mode is dominant at all radii except r = 10 r_H, where the m = 3 mode dominates.
