Source Code#

This page provided API docs for functionality which is typically not used by users, but is used internally in the PyAutoGalaxy source code.

These docs are intended for developers, or users doing non-standard computations using internal PyAutoFit objects.

Geometry Profiles#

`EllProfile`	An elliptical profile, which describes the geometry of profiles defined by an ellipse.
`SphProfile`	A spherical profile, which describes profiles with y and x centre Cartesian coordinates.

`OperateImage`	Packages methods which operate on the 2D image returned from the image_2d_from function of a light object (e.g. a LightProfile, Galaxy).
`LensCalc`	Computes lensing quantities from a deflection-angle callable and an optional potential callable.

`PointMass`
`PowerLawCore`	Represents a cored elliptical power-law density distribution
`PowerLawCoreSph`	Represents a cored spherical power-law density distribution
`PowerLawBroken`	Ell, homoeoidal mass model with an inner_slope and outer_slope, continuous in density across break_radius.
`PowerLawBrokenSph`	Ell, homoeoidal mass model with an inner_slope and outer_slope, continuous in density across break_radius.
`IsothermalCore`	Represents a cored elliptical isothermal density distribution, which is equivalent to the elliptical power-law density distribution for the value slope: float = 2.0
