ScarletDeblendContext

class lsst.meas.extensions.scarlet.ScarletDeblendContext(*, monotonicity: scl.operators.Monotonicity, observation: scl.Observation, deconvolved: scl.Image, footprints: list[scl.Footprint], footprintImage: scl.Image, config: ScarletDeblendConfig)

Bases: object

Context with parameters and config options for deblending

Attributes

monotonicity :

The monotonicity operator.

observation :

The observation for the entire coadd.

deconvolved :

The deconvolved image.

residual :

The residual image (observation - deconvolved mode convolved with difference kernel).

footprints :

The footprints in the deconvolved image.

footprintImage :

An indexed image of the scarlet footprints so that the value of a pixel gives the index + 1 of the footprints that contain that pixel.

config :

The configuration for the deblender.
