28. The smaller value reported in our previous work [10] was based on an incorrect extrapolation of trap frequencies to 100 times lower power. The radial trap frequency was strongly influenced by multiple intensity maxima in the optical focus.

32. According to Fig. 1, this fast ramp can dissociate weakly bound molecules at low density, but at high density we observed an atom-molecule conversion ≥ 90%.
33. At this point the cloud was sufficiently dilute that the final switch off of the field did not reconvert atoms into molecules.
