Measured Zeeman spectra at a magnetic field of 4.8 $\mu$T: excitation against detuning (kHz) as bars, with state preparation into $m_J = -1/2$ (blue) or $m_J = +1/2$ (red). The $S_{1/2}$ and $D_{5/2}$ sublevel labels printed below and above each peak are not drawn.
This panel was recovered from the published vector figure. The plot shown here is re-rendered for interactive viewing and analysis. See the paper for the original figure and full scientific context.
