FractionalDifference¶

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

Calculate (A-B)/B

Attributes Summary

`actionA`	Action which supplies vector A (`VectorAction`, default `<class 'lsst.analysis.tools.interfaces._actions.VectorAction'>`)
`actionB`	Action which supplies vector B (`VectorAction`, default `<class 'lsst.analysis.tools.interfaces._actions.VectorAction'>`)

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.
