(a) The temperatures of the trapped molecules as a function of the trapping voltages. The squares stand for the temperature in x (or y ) direction, the circles show the temperature in z direction, and the triangles indicate the 3D temperature of the trapped molecules. (b) The number of molecules in the trap relative to that of the molecules initially trapped. (c) The trap volume and (d) the density of the trapped molecules.
