Extended Data Fig. 2: Raw data for measurement of the difference in scattering length.

From: Observation of fermion-mediated interactions between bosonic atoms

Extended Data Fig. 2

Top, Measured radius of the caesium BEC with (red circles) and without (blue circles) lithium. Bottom, Measured BEC number with (red circles) and without (blue circles) lithium. At every field, the size of the BEC with lithium present is smaller than the corresponding measurement without lithium. However, overall experimental drift makes absolute comparison difficult. Calibrating each measurement point-by-point as described enables us to extract the difference in scattering length cleanly, as can be seen in Fig. 3b. Error bars are calculated as the standard error of the mean from multiple measurements.
