PySME - Spectroscopy Made Easier

Creators

  • 1. Uppsala University

Description

Over 20 years ago Valenti & Piskuonov developed the spectral synthesis library
Spectroscopy made easy (SME)[1] to simplify spectral analysis,
and it has been used in hundreds of works since.

PySME is a new Python frontend to the same library,
developed with the same goal in mind: Making spectroscopy easier for everyone.

PySME creates accurate, high-resolution synthetic spectra, based on a wide range of
stellar parameters, a linelist and a model atmosphere.
It can also be used the other way around. Give PySME an observation and it will
determine the best fit stellar parameters for that spectrum.
