Tools for extracting JWST NIRSpec MSA spectra directly from the telescope exposures

Under heavy construction....

Note

Please submit any questions/comments/problems you have through the Issues interface.

Documentation

Documentation will be here: https://msaexp.readthedocs.io/, though it's essentially just the module API for now.

The overall procedure is demonstrated in these notebooks:

• drizzled-nirspec.ipynb: Demo of new drizzling and combination code (0.6.0) with prism data from JWST program GO-1433 (PI: Dan Coe)
• process-rxj2129.ipynb: Demo with prism data from JWST program DD-2767 (PI: Pat Kelly)
• process-smacs0723.ipynb: Demo with medium resolution data from the JWST ERO-2736 program on the cluster SMACS-0723 (PI: Klaus Pontoppidon)

Try running the RXJ2129 demo notebook directly on GitHub in a Codespace:

1. Fork the repository from https://github.com/gbrammer/msaexp
2. "<> Code" pulldown > "Codespaces" > "+" to start the codespace
3. Wait for the initialization to complete
4. Navigate to the "docs/examples/" directory in the codespace
5. Open "process-rxj2129.ipynb" and run it
6. Commit to your forked repository any changes to the notebook itself or files created that you want to save outside the codespace
7. Profit!
