Detailed Description

Context manager which adds multiple overlapping sources and a parent.

Notes
-----
This is used as the return value for `TestDataset.addBlend`, and this is
the only way it should be used.

Member Function Documentation

◆ enter()

lsst.meas.base.tests.BlendContext.__enter__ ( self )

Definition at line 60 of file tests.py.

◆ exit()

◆ addChild()

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)
