a, T/TF and T (inset) against the remaining number of molecules N after 150 ms of evaporative cooling for various final trap depths. b, Plain evaporation during the hold time th after 150 ms of forced evaporation. The dashed line indicates the one-body decay and the inset sketches the evolution of the effective trap depth Utrap. c, T/TF and T (inset) during the hold time th. The error bars of N in a and b are the standard error of the mean of 5–20 repetitions. The error bars of T in a and c are the standard deviation from the fit to the averaged images. d–f, Azimuthally averaged optical density (OD) of the samples after 10 ms time of flight. The samples are prepared under the evaporation conditions I (d), II (e) and III (f). The images (insets) of the samples are averages from 5 (d), 20 (e) or 6 (f) individual images. The black lines show polylogarithmic fit functions, and the orange lines are fits of a Gaussian to the thermal wings of the sample.
