To learn more about the PSyGrid object or the Processing Pipeline API ini file, check out the [API Documentation](api.rst).

II. The Full POSYDON Processing Pipeline Experience

From A to Z, this tutorial shows you how to process, concatenate, down sample, plot grids and check failure rates, train interpolation objects and export the POSYDON dataset for population synthesis.

• The full POSYDON Processing Pipeline experience
  • Preparing the Pipeline initialization file
  • Setting-up and Running the Post Processing Pipeline
    • Exploring the visualization outputs

Congratulations! You’ve now mastered the POSYDON Processing Pipeline. To learn more about the PSyGrid object or the Processing Pipeline API ini file, check out the [API Documentation](api.rst) and the indepth components overview.

III. 1D Plotting Functionalities for POSYDON PSyGrids

Unlock the power of 1D plotting functionalities for POSYDON PSyGrids. This tutorial shows you how to easily visualize your single and binary star tracks leveraging the plot1D method of the PSyGrid object.

• 1D Plotting Functionalities for POSYDON PSyGrids
  • Example: the HMS-HMS gird
    • Plot one quantity as a function of another
    • Plot multiple quantities as a function of one quantity
    • Plot one or more quantities as a function of another for multiple tracks
    • Plot a third quantity as a color map
    • Plotting an Hertzsprung–Russell diagram
  • Example: the single HMS gird
    • Plotting an Hertzsprung–Russell diagram
  • Example: the single HeMS gird
    • Plotting an Hertzsprung–Russell diagram

IV. 2D Plotting Functionalities for POSYDON PSyGrids

Unlock the power of 2D plotting functionalities for POSYDON PSyGrids. This tutorial shows you how to easily visualize your single and binary star tracks leveraging the plot2D method of the PSyGrid object.

Advanced Tutorials

Export MESA Simulation Points to Rerun Using the Processing Pipeline

Learn how to export MESA simulation points to rerun using the Processing Pipeline.

• Export Rerun Grids with POSYDON Post Processing Pipeline
  • Preparing the Pipeline initialization file
  • Setting-up and Running the Post Processing Pipeline

Export Single Star PSyGrid Datasets

Learn how to export single star PSyGrid datasets. This is an advanced tutorial because it requires knowledge about the EEP code.

Note

POSYDON v2.0.0 does not embed a python interface to compute EEPs but relies on the Fortran code of Aaron Dotter (2016). Future POSYDON code releases will include a python interface to compute EEPs and embed the export of single stellar grid into the post-processing pipeline.

• Processing Single Stars with POSYDON
  • Generating the EEP history files
  • Creating the PSyGrid Object and Computing the Processed Quantities
    • Exploring the PSyGrid obejct
