Inferred gravitational potential at height z = 400 pc for all data samples (s from −5 to 5 and ). The markers and vertical lines show the mean and standard deviations as derived from jackknifing, where the colours represent the three fixed values for the height of the Sun (Z_⊙ = {0, 10, 20} pc). The grey band represents the baryonic model, including a dark matter density of 0.011 ± 0.003 M_⊙ pc⁻³.
