HsmPsfMomentsConfig#

class lsst.meas.extensions.shapeHSM.HsmPsfMomentsConfig(*args, **kw)#

Bases: HsmMomentsConfig

Configuration for HSM adaptive moments measurement for PSFs.

Attributes Summary

`addFlux`	Store measured flux? (`bool`, default `False`)
`doMeasure`	whether to run this plugin in single-object mode (`bool`, default `True`)
`roundMoments`	Use round weight function? (`bool`, default `False`)
`subtractCenter`	Subtract starting center from x/y outputs? (`bool`, default `False`)
`useSourceCentroidOffset`	If True, then draw the PSF to be measured in the coordinate system of the original image (the PSF model origin - which is commonly the PSF centroid - may end up near a pixel edge or corner).

Methods Summary

Subclass hook for computing defaults.

Attributes Documentation

doMeasure#: whether to run this plugin in single-object mode (bool, default True)

subtractCenter#: Subtract starting center from x/y outputs? (bool, default False)

useSourceCentroidOffset#: If True, then draw the PSF to be measured in the coordinate system of the original image (the PSF model origin - which is commonly the PSF centroid - may end up near a pixel edge or corner). If False, then draw the PSF to be measured in a shifted coordinate system such that the PSF model origin lands precisely in the center of the central pixel of the PSF image. (bool, default False)

Methods Documentation

setDefaults()#: Subclass hook for computing defaults.

Notes#

Derived Config classes that must compute defaults rather than using the Field instances’s defaults should do so here. To correctly use inherited defaults, implementations of setDefaults must call their base class’s setDefaults.
