A Python package for plotting and interacting with echelle diagrams.

Project description



Echelle is a Python package for plotting and interacting with echelle diagrams. In an echelle diagram, the amplitude spectrum of a star is stacked in equal slices of delta nu, the large separation.


pip install echelle or download the git repository and python install


For a dynamic interface:

from echelle import interact_echelle
interact_echelle(frequency, power, dnu_min, dnu_max)

If you're using echelle in a Jupyter notebook, I suggest calling %matplotlib notebook first.

To plot a non-interactive echelle diagram,

from echelle import plot_echelle
plot_echelle(frequency, power, dnu)

See the example.ipynb for common usage!


If you make use of echelle in your work, please consider citing the Zenodo listing

  author       = {Daniel Hey and
                  Warrick Ball},
  title        = {{Echelle: Dynamic echelle diagrams for

  year         = 2020,

  version      = {1.4},
  doi          = {10.5281/zenodo.3629933},
  url          = {}

Thanks to Adam Hamilton for making the echelle gif!
