General notes to the user

• Make sure the HEASoft and WCSTools are correctly installed and initialized (see install guide). Without these tools, you won’t be able to run the pipeline.
• Make sure you are using Python 3.7 or later, and that all required modules are installed properly. The script will emit an error message if a module or package is missing.
• Check the output after each step.
• Questions/problems can be reported through GitHub issues.
