Superposed phase spiral for different angular momenta with Gaia DR3 data. We select stars with ϕ ∈ [ − 20, 20]deg. We use bins of ΔL_Z = 200 km s⁻¹ kpc and centres of bins separated by 100 km s⁻¹ kpc, from L_Z = −1300 km s⁻¹ kpc (bluer lines) to L_Z = −2500 km s⁻¹ kpc (redder lines), as indicted in the legend. In parenthesis, we give an indicative measure of the guiding radius (in kpc), assuming a flat circular velocity curve.
