__call__()

lsst.pipe.tasks.dataFrameActions._actions.NanoJansky.__call__	(		self,
			df,
		**	kwargs )

Reimplemented from lsst.pipe.tasks.dataFrameActions._actions.SingleColumnAction.

Definition at line 75 of file _actions.py.

    def __call__(self, df, **kwargs):
        dataNumber = super().__call__(df, **kwargs)
        if not (fluxMag0 := kwargs.get('fluxMag0')):
            fluxMag0 = 1/np.power(10, -0.4*self.coadd_zeropoint)
        return self.ab_flux_scale * dataNumber / fluxMag0
 

setDefaults()

lsst.pipe.tasks.dataFrameActions._actions.NanoJansky.setDefaults

(

self

)

Subclass hook for computing defaults.

Notes
-----
Derived `~lsst.pex.config.Config` classes that must compute defaults
rather than using the `~lsst.pex.config.Field` instances's defaults
should do so here. To correctly use inherited defaults,
implementations of ``setDefaults`` must call their base class's
``setDefaults``.

Reimplemented from lsst.pex.config.config.Config.

    def setDefaults(self):
        super().setDefaults()
        self.cache = True  # cache this action for future calls
