As of v0.2.3, PyTeCK cannot handle ChemKED files with uncertainties (at least in ignition delay, and likely other quantities).
For example, in `eval_model`,
```

Very nice algorithm, and though we'd want to test it more, I consider it among the best candidates for operational use.
To that end, one of the main requirements communicated to me was the algorithm …
