FieldAngleFrame

pydantic model lsst.images.FieldAngleFrame

An angular coordinate frame that maps a camera onto the sky about its boresight.

Notes

The transform between a FocalPlaneFrame and a FieldAngleFrame includes optical distortions but no rotation. It may include a parity flip.

Parameters:

data (Any)

Fields:

• frame_type (Literal['FIELD_ANGLE'])

• instrument (str)

• visit (int | None)

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

Discriminator for the frame type.

field instrument: str [Required]

Name of the instrument.

field visit: int | None = None

ID of the visit. May be unset in contexts where there is no visit or only a relevant single visit.

deserialize()

Convert a serialized frame to an in-memory one.

Return type:

FieldAngleFrame

serialize()

Return a Pydantic-serializable version of this Frame.

Return type:

FieldAngleFrame

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).
