Pixelizations#
Pixelization#
Groups all of the individual components used to reconstruct a galaxy via a
pixelization (an ImageMesh
, Mesh
and Regularization
)
The Pixelization
API documentation provides a comprehensive description of how pixelizaiton objects work and
their associated API.
It is recommended you read this documentation before using pixelizations.
Pairs a 2D grid of (y,x) coordinates with a 2D mesh, which can be combined with a |
Image Mesh [ag.image_mesh]#
Computes an image-mesh by overlaying a uniform grid of (y,x) coordinates over the masked image that the pixelization is fitting. |
|
Computes an image-mesh by computing the Hilbert curve of the adapt data and drawing points from it. |
|
Computes a balanced image-mesh by computing the Hilbert curve of the adapt data and drawing points from it. |
|
Computes an image-mesh by running a weighted KMeans clustering algorithm. |
Mesh [ag.mesh]#
A uniform mesh of rectangular pixels, which without interpolation are paired with a 2D grid of (y,x) coordinates. |
|
An irregular mesh of Delaunay triangle pixels, which using linear barycentric interpolation are paired with a 2D grid of (y,x) coordinates. |
|
An irregular mesh of Voronoi pixels, which using no interpolation are paired with a 2D grid of (y,x) coordinates. |
|
An irregular mesh of Voronoi pixels, which using no interpolation are paired with a 2D grid of (y,x) coordinates. |
Regularization [ag.reg]#
Regularization which uses the neighbors of the mesh (e.g. |
|
Regularization which uses the derivatives at a cross of four points around each pixel centre and a single value to smooth an inversion's solution. |
|
Regularization which uses the neighbors of the mesh (e.g. |
|
Regularization which uses the derivatives at a cross of four points around each pixel centre and values adapted to the data being fitted to smooth an inversion's solution. |
Settings#
The settings of an Inversion, customizing how a linear set of equations are solved for. |
Mapper#
|
Factory which given input MapperGrids and Regularization objects creates a Mapper. |
