Different data sets as described in the condition column; the principle row is the data set principally analysed in this article. It is the only row to include the antiproton-suppressing elliptical cut. The No Bias row reports data taken with the bias electric fields off. The ‘Well alternated’ rows come from trapping trials in which the Bias-Right and Bias-Left conditions were strictly alternated. As not every trial trapped antiatoms, the data are not strictly alternated. The selection column indicates if the row’s data set is a subset, superset or disjoint set relative to the principle data set. Some of the rows include both a subset of the principle data and some additional data; these rows are designated Sub/Super. All rows include the |z|<136 mm cut unless otherwise noted.
