Who is using Python

“Sometimes the middle of the herd is a good place to be.”

(In response to the question “Why spend time migrating to Python?” at a Users Committee meeting)

That was several years ago and in the interim the momentum toward Python in astronomy has only grown. The ease of interfacing C / C++ / FORTRAN means many organizations are using Python user front-ends with a combination of compiled code + Python on the back-end.

• Radio / Submm (NRAO, ESO, JAOJ, CSIRO): CASA
• IR: HIPE (Herschel Interactive Processing Environment)
• Optical: STSci (PyRAF, PyFITS)
• Optical: Gemini IRAF package - new development in Python
• Optical: ESO PyMidas
• X-ray: Chandra CIAO and Sherpa
• Gamma-ray: Fermi Science Analysis tools
