runDataRef()

def lsst.cp.pipe.linearity.MeasureLinearityTask.runDataRef	(		self,
			dataRef
	)

Run new linearity code for gen2.

Parameters
----------
dataRef : `lsst.daf.persistence.ButlerDataRef`
    Input dataref for the photon transfer curve data.

Returns
-------
results : `lsst.pipe.base.Struct`
    The results struct containing:

    ``outputLinearizer`` : `lsst.ip.isr.Linearizer`
        Final linearizer calibration.
    ``outputProvenance`` : `lsst.ip.isr.IsrProvenance`
        Provenance data for the new calibration.
