Constructor & Destructor Documentation

def lsst.meas.base.references.CoaddSrcReferencesTask.__init__	(		self,
			butler = None,
			schema = None,
			kwargs
	)

Initialize the task.

Additional keyword arguments (forwarded to BaseReferencesTask.__init__):

• schema: the schema of the detection catalogs used as input to this one
• butler: a butler used to read the input schema from disk, if schema is None The task will set its own self.schema attribute to the schema of the output merged catalog.
