source.energy = openmc.stats.Discrete([356012.9, 80997.9, 302850.8, 383848.5, 276398.9],[0.6205,0.329,0.1834,0.0894,0.0716])  
source.strength = 1e4  
what’s the final source strength?  
For example, will the source’s strength, which energy equal to 356012.9eV, will either be 1E4 \* 0.6205, or be 1E4 \* 0.6205 / (0.6205+0.0.329+0.1834+0.0894+0.0716) ?

I run an example, and it was normalization?
