Member Function Documentation

◆ _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.

76 def _fromFootprintList(self, fpList):
77 """Compute a defect list from a footprint list.

79 Parameters
80 ----------
81 fpList : `list` of `lsst.afw.detection.Footprint`
82 Footprint list to process.

84 Returns
85 -------
86 defects : `list` of `lsst.meas.algorithms.Defect`
87 List of defects.

◆ _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.

Definition at line 98 of file reinterpolate_pixels.py.

101 Parameters

103 exposure : `lsst.afw.image.Exposure`
104 Exposure to process.
105 defectList : `list` of `lsst.meas.algorithms.Defect`
106 List of defects to interpolate over.

◆ run()

lsst.meas.algorithms.reinterpolate_pixels.ReinterpolatePixelsTask.run ( self,
