METHODOLOGICAL INFORMATION

1. Description of methods used for collection/generation of data: 
Awaiting publication in New Journal of Physics
https://doi.org/10.48550/arXiv.2205.09457


2. Methods for processing the data: 
The experimental measurements of |f=3> or |f=1> population are the fraction of experimental runs that retain an atom.
The hyperfine spin state is mapped onto the retention probability using a resonant pushout pulse, as mentioned in the main body of the text.

3. Instrument- or software-specific information needed to interpret the data: 
Numerical calculations performed in Python 3.5. 
Simulations of the Raman Hamiltonian use the QuTiP module: https://qutip.org/

4. Standards and calibration information, if appropriate: 

5. Environmental/experimental conditions: 

6. Describe any quality-assurance procedures performed on the data: 

7. People involved with sample collection, processing, analysis and/or submission: 
S Spence, R V Brooks, D K Ruttley, A Guttridge.
