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 Experince

From A to Z, this tutorial shows you how to process, concatenate, downsample, plot the grids and check failure rate, train the interpolation object and export the POSYDON dataset for population synthesis.

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

Congratulations! You now master 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

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 advaced tuotorial because it requires knowledge about the EEP code.

Note

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

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