Spatially resolved jittering across the solar disk. RMS values for radial velocities of idealized Fe I lines at λ620 nm are shown for lines of different strengths at excitation potentials χ = 1 and 5 eV. The bold curves show averages over the small simulation area: solid for strong lines; dashed for weak. The curves for χ = 1 eV are black and for 5 eV are red. Multiple thin lines illustrate the differences among different azimuth angles at each center-limb position.
