Extended Data Fig. 2: Escape curve for 130 s ramp-down.
From: Observation of the effect of gravity on the motion of antimatter

The Pdn values are plotted versus bias for the three trial sets having biases 0 g, −1 g, and −2 g. These biases were chosen after the 20 s ramp results had been examined. Apart from the slower ramp, the experimental and analysis procedures were identical to those for the 20 s protocol. The 20 s data and simulations for both ramp times are also shown for comparison. Note that the simulated escape curve for the 130 s ramp has a steeper transition region than for the 20 s ramp, and the balance point (Pdn = 0.5) is not at a bias of precisely −1 g, as described in the text.
