Detailed Description

Split blended sources into individual sources.

This task has no return value; it only modifies the SourceCatalog in-place.

Constructor & Destructor Documentation

__init__()

def lsst.meas.deblender.sourceDeblendTask.SourceDeblendTask.__init__	(		self,
			schema,
			peakSchema = None,
		**	kwargs
	)

Create the task, adding necessary fields to the given schema.

Parameters
----------
schema : `lsst.afw.table.Schema`
    Schema object for measurement fields; will be modified in-place.
peakSchema : `lsst.afw.table.peakSchema`
    Schema of Footprint Peaks that will be passed to the deblender.
    Any fields beyond the PeakTable minimal schema will be transferred
    to the main source Schema. If None, no fields will be transferred
    from the Peaks
**kwargs
    Additional keyword arguments passed to ~lsst.pipe.base.task

Returns whether a Footprint is large

'Large' is defined by thresholds on the area, size and axis ratio.
These may be disabled independently by configuring them to be non-positive.

This is principally intended to get rid of satellite streaks, which the

(e.g., multiple large HeavyFootprints can chew up memory).
