subplot_fit_imaging(fit, output_path=None, output_format=None, colormap=None, plane_index=None, image_plane_lines=None, image_plane_line_colors=None, source_plane_lines=None, source_plane_line_colors=None, title_prefix=None)#

Produce a 12-panel subplot summarising an imaging fit.

Arranges the following panels in a 3 × 4 grid:

  • Data

  • Model image

  • Signal-to-noise map

  • Source plane image (max zoom)

  • Lens-light model image

  • Lens-light-subtracted image (source scale)

  • Source model image (source scale)

  • Source plane image (mid zoom — 2× wider than max zoom, square, shrunk uniformly so all edges stay inside the no-zoom extent)

  • Normalised residual map (symmetric scale)

  • Normalised residual map clipped to ± 1 σ

  • Chi-squared map

  • Source plane image (full extent)

For single-plane tracers the function delegates to subplot_fit_x1_plane, which uses a simpler 2 × 3 layout.

Parameters:

  • fit (FitImaging) – The imaging fit to visualise.

  • output_path (Optional[str]) – Directory in which to save the figure. If None the figure is not saved to disk.

  • output_format (str) – Image format passed to save_figure (e.g. "png", "pdf").

  • colormap (Optional[str]) – Matplotlib colormap name applied to all image panels.

  • plane_index (Optional[int]) – Index of the source plane to use for the source-scale panels. Defaults to the final plane in the tracer.
