The times and vertical (y) annihilation locations (green dots) of 10,000 simulated antihydrogen atoms in the decaying magnetic fields. There is a tendency for the anti-atoms to annihilate in the bottom half of the trap, as shown by the black solid line. The blue dotted line includes the effects of detector azimuthal smearing on the average; the smearing reduces the effect of gravity observed in the data. The red circles are the annihilation times and locations for 434 real anti-atoms, as measured by the particle detector (A. E. Charman, the ALPHA Collaboration)
