The in situ axial density profiles for the weakly interaction Bose gas of ⁸⁷Rb atoms at different temperatures. The solid lines show the result obtained from the Yang–Yang equations. The values of the chemical potentials are indicated by the harmonically trapping potentials. The experimental data show a good agreement with the theoretical prediction from the Yang–Yang equation.^{[ 55 ]}
