This is a repository with code and data analysis notebook for the X-ray binary Vela X-1 presented in the paper: SAS in ESA Datalabs: A New Platform for XMM-Newton Analysis.
Check ReadMeTools.md for details on the Python functions. Check ReadMeScripts.md for details on the Python scripts.
- CaseStudy.ipynb: Jupyter Lab Notebook with the pySAS data extraction and visualisation on Vela X-1.
- tools: Python utility functions needed for plotting and visualisation.
- scripts: Python scripts to run looped SAS tasks to extract data.
If running the Notebook on ESA Datalabs inside the XMM-SAS datalab, no pre-requisites are required. Everything is already pre-configured inside the datalab!
To run the Notebook locally you need Python 3.10 or above and standard packages/software listed in requirements.txt.
The Docker container environment used in the XMM-SAS Datalab has HEASOFT built from source in order to also have xspec available (MIT license). You will need SAS version 21.0.0 to have access to pysas-wrapper (GPL-3.0 license) and SAS commands.
