TractFrame

pydantic model lsst.images.TractFrame

The pixel coordinates of a tract: a region on the sky used for coaddition, defined by a ‘skymap’ and split into ‘patches’ that share a common pixel grid.

Parameters:

data (Any)

Fields:

• bbox (lsst.images._geom.Box)

• frame_type (Literal['TRACT'])

• skymap (str)

• tract (int)

field bbox: Box [Required]

Bounding box of the full tract.

field frame_type: Literal['TRACT'] = 'TRACT'

Discriminator for the frame type.

field skymap: str [Required]

Name of the skymap.

field tract: int [Required]

ID of the tract within its skymap.

deserialize()

Convert a serialized frame to an in-memory one.

Return type:

TractFrame

serialize()

Return a Pydantic-serializable version of this Frame.

Return type:

TractFrame

standardize_x(x)

Coerce x coordinates into their standard range.

Parameters:

x (TypeVar(T, bound= float | ndarray)) – Coordinates to standardize.

Return type:

TypeVar(T, bound= float | ndarray)

standardize_y(y)

Coerce y coordinates into their standard range.

Parameters:

y (TypeVar(T, bound= float | ndarray)) – Coordinates to standardize.

Return type:

TypeVar(T, bound= float | ndarray)

property unit: UnitBase

Units of the coordinates in this frame (astropy.units.UnitBase).
