Calculated 2-d Fields

lsst.images.fields Package

Fields are 2-d parametric functions used to represent some property of an image, like a background model or a spatially-varying aperture correction.

Functions

field_from_legacy(legacy_bounded_field[, ...])	Convert a legacy lsst.afw.math.BoundedField subclass to a BaseField object.
field_from_legacy_background(legacy_background)	Convert a legacy lsst.afw.math.Background or lsst.afw.math.BackgroundList instance to a BaseField object.
field_from_legacy_photo_calib(...[, ...])	Convert a legacy lsst.afw.image.PhotoCalib into a BaseField object.

Classes

BaseField()	An abstract base class for parametric or interpolated 2-d functions, generally representing some sort of calculated image.
ChebyshevField(bounds, coefficients, *[, unit])	A 2-d Chebyshev polynomial over a rectangular region.
ChebyshevFieldSerializationModel	Serialization model for ChebyshevField.
ProductField(operands)	A field that multiplies other fields lazily.
ProductFieldSerializationModel	Serialization model for ProductField.
SplineField(bounds, data, *, y, x[, unit])	A 2-d Akima spline interpolation of data on a regular grid.
SplineFieldSerializationModel	Serialization model for SplineField.
SumField(operands)	A field that sums other fields lazily.
SumFieldSerializationModel	Serialization model for SumField.
