mescla.types.EndMembers

class mescla.types.EndMembers(data, species=None, index=None, units='mg/L', sigma=None, censored=None)

Bases: ChemTable

Chemistry of the candidate source waters (end-members).

Their sigma usually needs to be larger than that of the mixed samples: end-member uncertainty is dominated by spatial and temporal variability and by conceptual error, not by the laboratory (Carrera et al., 2004).

Parameters:

• data (ndarray)

• species (tuple[str, ...])

• index (tuple[str, ...])

• units (Any)

• sigma (ndarray | None)

• censored (ndarray | None)

property labels: tuple[str, ...]

Alias for index.
