SOFIA Data Analysis Cookbooks

Aim: These documents provide simple recipes (i.e., descriptions and guided examples) for common data analysis objectives using SOFIA processed data.

Skill level: These are generally written for a graduate student audience. Some of the recipes are Jupyter notebooks designed for a researcher with a working knowledge of the numpy, scipy, matplotlib, and astropy. For more general information on these tools see Jupyter notebooks usage and installation and the Python Data Science Handbook.

Contact us: For questions not addressed in these notebooks or the SOFIA handbooks, please contact us at the sofia_help@sofia.usra.edu.

Suggestions: We also encourage you to submit any comments or suggestions on these notebooks through a new Github “Issue”.

Contribute: If you have some code that you think other SOFIA users might be interested in, please contact us!!!

Additional Resources: For additional examples of data analysis of infrared data see the Data Analysis Talks for JWST data.
