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:
objectContext 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.
