CalcSn

class lsst.analysis.tools.actions.vector.CalcSn(*args, **kw)

Bases: VectorAction

Calculate the signal-to-noise ratio from a single flux vector.

Attributes Summary

fluxType

Flux type (vector key) to calculate the S/N.

uncertaintySuffix

Suffix to add to fluxType to specify the uncertainty column (str, default 'Err')

Methods Summary

__call__(data, **kwargs)

Call self as a function.

getInputSchema()

Return the schema an AnalysisAction expects to be present in the arguments supplied to the __call__ method.
