.. _sphx_glr_auto_gallery_data:

The curated data
----------------

Every dataset of each gas against the fitted model, where the data cover the spectrum,
and how independent datasets check one another.

Static values (the polarizability at zero frequency) sit at the right edge. The gaps are where new data would help most.">
