Left first row: determination of resonances radii at different times from a Fourier analysis on the whole disc. Horizontal lines show the pattern speed Ωp obtained from the maximum of the spectrogram, the solid curve is Ω(R), dashed curve is , and dash-dotted curve is . Vertical lines are the radii of the ILR (blue), corotation (orange), and OLR (green). Left second row: strength of π-periodic non axisymmetries of the whole disc as a function of radius at the same times as in the first row. Right plot: resulting bar speed and resonance radii estimation as a function of time.
