Point Sources#
A collection of the data component that can be used for point-source model-fitting, for example fitting the observed positions of a a strongly lensed quasar or supernovae or in strong lens cluster modeling, where there may be many tens or hundreds of individual source galaxies each of which are modeled as a point source. |
|
Abstract class to fit the positions of a point source dataset using a Tracer object with an image-plane chi-squared, where the specific implementation of the image-plane chi-squared is defined in the sub-class. |
|
Fits the fluxes of a a point source dataset using a Tracer object, where every model flux of the point-source is compared with its observed flux. |
|
Determine the image plane coordinates that are traced to be a source plane coordinate. |
|
Fits a lens model to a point source dataset (e.g. positions, fluxes, time delays) via a non-linear search. |
