	Results from simulations of the merging trajectory of Rb and Cs atoms in the combined potential of merging optical tweezers. This dataset contains the data shown in Fig S4(a)-(c) for a trajectory ending in perfectly overlapped tweezers. Note: the position data in Fig S4(a)(i)-(ii) has been multipled by -1 compared to the data in this dataset.
	
Figure S4d data.csv
	Results from simulations of the merging trajectory of Rb and Cs atoms in the combined potential of merging optical tweezers. This dataset contains the data shown in Fig S4(d) which is the effect of misalignment of the tweezers on the interatomic speed at the avoided crossing.

METHODOLOGICAL INFORMATION

1. Description of methods used for collection/generation of data: 
Described in the manuscript found at: https://arxiv.org/abs/2302.07296 

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 and fits performed in Python 3.9.

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: 
Daniel K. Ruttley, Alexander Guttridge, Stefan Spence, Robert C. Bird, C. Ruth Le Sueur, Jeremy M. Hutson, and Simon L. Cornish.
