addChild()

def lsst.meas.base.tests.BlendContext.addChild	(		self,
			instFlux,
			centroid,
			shape = None
	)

Add a child to the blend; return corresponding truth catalog record.

instFlux : `float`
    Total instFlux of the source to be added.
centroid : `lsst.geom.Point2D`
    Position of the source to be added.
shape : `lsst.afw.geom.Quadrupole`
    Second moments of the source before PSF convolution.  Note that
    the truth catalog records post-convolution moments)
