GUIBRUSHR.GUI.Input_Output_Panels.Input_Panels.TabPanels.Frame_Retrieval_Analysis.Tab_Analysis.FrameCornerPlot.plot_pmcmcg module

PMCMCG Corner Plot Generator

This module generates corner plots for MCMC analysis results using different plotting libraries (corner, pygtc). It processes retrieval data and creates visualization plots with parameter distributions and confidence intervals.

The script is designed to be called from command line with specific arguments and maintains the exact sequence of operations for compatibility with the existing pipeline.

GUIBRUSHR.GUI.Input_Output_Panels.Input_Panels.TabPanels.Frame_Retrieval_Analysis.Tab_Analysis.FrameCornerPlot.plot_pmcmcg.db_value_corner_plot(lista_par, lista_par_fix, best_fit_parameters, error_list, value_fix, target_kp, target_ecc, target_opi, target_t_eq)[source]

Extract database values and median values for corner plot parameters.

This function checks which parameters are available in the parameter lists and extracts corresponding target values and median values for plotting.

Parameters:

  • lista_par – List of fitted parameters

  • lista_par_fix – List of fixed parameters

  • best_fit_parameters – Median values for fitted parameters

  • error_list – Error values for fitted parameters

  • value_fix – Values for fixed parameters

  • target_kp – Target K_p value

  • target_ecc – Target eccentricity

  • target_opi – Target omega value

  • target_t_eq – Target equilibrium temperature

Returns:

Contains values_db (list), values_median (list), index (list),

T0_f (float), et_f (float)

Return type:

tuple

GUIBRUSHR.GUI.Input_Output_Panels.Input_Panels.TabPanels.Frame_Retrieval_Analysis.Tab_Analysis.FrameCornerPlot.plot_pmcmcg.find_param_arr(name, lista_par, lista_par_fix, best_fit_parameters, error_list, value_fix, value=None)[source]

Find parameter value and error from parameter lists.

Searches for a parameter in the fitted parameters list first, then in the fixed parameters list, and finally uses the provided default value.

Parameters:

  • name – Parameter name to search for

  • lista_par – List of fitted parameters

  • lista_par_fix – List of fixed parameters

  • best_fit_parameters – Median values for fitted parameters

  • error_list – Error values for fitted parameters

  • value_fix – Values for fixed parameters

  • value – Default value to use if parameter not found

Returns:

Object containing parameter value and error

Return type:

ValueErrorTP

GUIBRUSHR.GUI.Input_Output_Panels.Input_Panels.TabPanels.Frame_Retrieval_Analysis.Tab_Analysis.FrameCornerPlot.plot_pmcmcg.plot_corner(arr1, lista_parametri, style_corner='black', figsize=None, title_fmt='.2f', smooth=1.0, show_titles=True, truth_values=None, levels=30, quantiles=None, bins=50)[source]

Create a publication-ready corner plot.

Parameters:

  • arr1 (array-like) – MCMC samples with shape (nsamples, ndim)

  • lista_parametri (list) – Parameter labels (supports LaTeX)

  • style_corner (str) – Style options: - Contour styles (lines + datapoints): “black”, “orange”, “blue”, “purple”, “green”, “brown” - Filled styles (filled contours, no datapoints): “blue_cmap”, “orange_cmap” - Colormap style (density gradient): “gnuplot2”

  • figsize (tuple, optional) – Figure size. If None, auto-calculated based on ndim

  • title_fmt (str) – Format string for title values

  • smooth (float) – Smoothing factor for contours

  • show_titles (bool) – Show parameter values in titles

  • truth_values (list, optional) – True values to overplot

  • levels (int) – Number of contour levels for colormap styles (default 30)

  • quantiles (list) – Quantiles to show (default [0.16, 0.5, 0.84])

  • bins (int) – Number of bins for 2D histograms

Returns:

figure

Return type:

matplotlib.figure.Figure
