subplot_fit_imaging_of_galaxy(fit, galaxy_index, output_path=None, output_format=None, colormap='default', use_log10=False, positions=None, residuals_symmetric_cmap=True, title_prefix=None)#

Create a three-panel subplot focused on a single galaxy contribution.

Shows the observed data alongside the subtracted image and model image for the galaxy at galaxy_index in the fitted galaxy list. This is useful for inspecting the contribution of individual galaxies when multiple galaxies are being fitted simultaneously.

Parameters:

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

  • galaxy_index (int) – Index into fit.galaxies selecting which galaxy to highlight.

  • output_path (str or None) – Directory in which to save the figure. None → plt.show().

  • output_format (str) – File format, e.g. "png".

  • colormap (str) – Matplotlib colormap name, or "default".

  • use_log10 (bool) – Apply a log₁₀ stretch to the plotted values.

  • positions (array-like or None) – Point positions to scatter-plot over each panel.

  • residuals_symmetric_cmap (bool) – Reserved for future symmetric-colormap support (currently unused).
