Data for an entire blend. Attributes ---------- origin: The lower bound of the blend's bounding box. shape: The shape of the blend's bounding box. sources: Data for the sources contained in the blend, indexed by the source id. psf_center: The location used for the center of the PSF for the blend. psf: The PSF of the observation. bands : `list` of `str` The names of the bands. The order of the bands must be the same as the order of the multiband model arrays, and SEDs.
dict lsst.scarlet.lite.io.ScarletBlendData.as_dict | ( | self | ) |
Return the object encoded into a dict for JSON serialization Returns ------- result: The object encoded as a JSON compatible dict
Definition at line 258 of file io.py.

Convert a scarlet lite blend into a persistable data object Parameters ---------- blend: The blend that is being persisted. psf_center: The center of the PSF. Returns ------- blend_data: The data model for a single blend.
Definition at line 392 of file io.py.
ScarletBlendData lsst.scarlet.lite.io.ScarletBlendData.from_dict | ( | cls, | |
dict | data, | ||
DTypeLike | dtype = np.float32 ) |
Reconstruct `ScarletBlendData` from JSON compatible dict. Parameters ---------- data: Dictionary representation of the object dtype: Datatype of the resulting model. Returns ------- result: The reconstructed object
Definition at line 278 of file io.py.
Blend lsst.scarlet.lite.io.ScarletBlendData.minimal_data_to_blend | ( | self, | |
np.ndarray | model_psf, | ||
DTypeLike | dtype ) |
Convert the storage data model into a scarlet lite blend Parameters ---------- model_psf: PSF in model space (usually a nyquist sampled circular Gaussian). dtype: The data type of the model that is generated. Returns ------- blend: A scarlet blend model extracted from persisted data.
Definition at line 307 of file io.py.
Blend lsst.scarlet.lite.io.ScarletBlendData.to_blend | ( | self, | |
Observation | observation ) |
Convert the storage data model into a scarlet lite blend Parameters ---------- observation: The observation that contains the blend. If `observation` is ``None`` then an `Observation` containing no image data is initialized. Returns ------- blend: A scarlet blend model extracted from persisted data.
Definition at line 332 of file io.py.
