◆ _fromFootprintList()

lsst.meas.algorithms.reinterpolate_pixels.ReinterpolatePixelsTask._fromFootprintList	(		self,
			fpList )

protected

Compute a defect list from a footprint list.

Parameters
----------
fpList : `list` of `lsst.afw.detection.Footprint`
    Footprint list to process.

Returns
-------
defects : `list` of `lsst.meas.algorithms.Defect`
    List of defects.

Notes
-----
By using `itertools.chain.from_iterable()`, the nested iterables are merged into a flat iterable,
allowing convenient iteration over all `lsst.meas.algorithms.Defect` objects.

Definition at line 76 of file reinterpolate_pixels.py.

◆ _interpolateDefectList()

lsst.meas.algorithms.reinterpolate_pixels.ReinterpolatePixelsTask._interpolateDefectList	(	self,
		exposure,
		defectList )

protected

Interpolate over defects specified in a defect list.

Parameters
----------
exposure : `lsst.afw.image.Exposure`
    Exposure to process.
defectList : `list` of `lsst.meas.algorithms.Defect`
    List of defects to interpolate over.

Notes
-----
``exposure`` is modified in place and will become the reinterpolated exposure.
When reinterpolating following the interpolation in ip_isr, be aware that the masks are intentionally
left grown as a side-effect of that interpolation.

◆ run()

Parameters
----------
