Constructor & Destructor Documentation

__init__()

def lsst.pipe.tasks.scaleZeroPoint.SpatialScaleZeroPointTask.__init__	(		self,
		*	args,
		**	kwargs
	)

Construct a ScaleZeroPointTask

Reimplemented from lsst.pipe.tasks.scaleZeroPoint.ScaleZeroPointTask.

Definition at line 221 of file scaleZeroPoint.py.

Member Function Documentation

computeImageScaler()

def lsst.pipe.tasks.scaleZeroPoint.SpatialScaleZeroPointTask.computeImageScaler	(		self,
			exposure,
			dataRef
	)

Compute image scaling object for a given exposure.

@param[in] exposure: exposure for which scaling is desired. Only wcs and bbox are used.
@param[in] dataRef: dataRef of exposure
                    dataRef.dataId used to retrieve all applicable fluxMag0's from a database.
@return a SpatialImageScaler

Reimplemented from lsst.pipe.tasks.scaleZeroPoint.ScaleZeroPointTask.

Definition at line 241 of file scaleZeroPoint.py.

run()

def lsst.pipe.tasks.scaleZeroPoint.SpatialScaleZeroPointTask.run	(		self,
			exposure,
			dataRef
	)

Scale the specified exposure to the desired photometric zeropoint

@param[in,out] exposure: exposure to scale; masked image is scaled in place
@param[in] dataRef: dataRef for exposure

@return a pipeBase.Struct containing:
- imageScaler: the image scaling object used to scale exposure
