IsolatedSource

class lsst.meas.extensions.scarlet.IsolatedSource(model: Image, peak: tuple[int, int], metadata: dict | None = None)

Bases: SourceBase

A scarlet source representation for isolated sources.

Attributes Summary

bands	The ordered list of bands in the full source model.
bbox	The bounding box of the source in the full Blend.
component	The single component of this isolated source.
peak	The (y, x) coordinates of the peak pixel within the model.

Methods Summary

from_footprint(footprint, mCoadd, dtype[, ...])	Create an IsolatedSource from a footprint in a multiband coadd.
get_model()	Get the full 3D (band, y, x) model of the source.
to_data()	Convert to a ScarletSourceData representation.

Attributes Documentation

bands

The ordered list of bands in the full source model.

bbox

Methods Documentation

static from_footprint(footprint: Footprint, mCoadd: MultibandExposure, dtype: type[Any] | dtype[Any] | _SupportsDType[dtype[Any]] | tuple[Any, Any] | list[Any] | _DTypeDict | str | None, metadata: dict | None = None) → IsolatedSource

Create an IsolatedSource from a footprint in a multiband coadd.

Parameters

footprint :

The footprint of the source in the multiband coadd.

mCoadd :

The multiband coadd containing the source.

dtype :

The desired data type for the source model.

metadata :

Optional metadata to store with the source.

Returns

source :

The isolated source represented as a ScarletSource.

get_model() → Image

Get the full 3D (band, y, x) model of the source.

Returns

model :

The 3D (band, y, x) model of the source.

to_data() → IsolatedSourceData

Convert to a ScarletSourceData representation.

Returns

source_data :

The source represented as a ScarletSourceData.
