Baseline Removal

This example shows how to remove a baseline from a 1D signal using the pybaselines library.

Create a signal

import hyperspy.api as hs
s = hs.data.two_gaussians()

Remove baseline using remove_baseline():

s2 = s.remove_baseline(method="aspls", lam=1E7, inplace=False)

Plot the signal and its baseline:

(s + (s-s2) * 1j).plot()
# Choose the second figure as gallery thumbnail:
# sphinx_gallery_thumbnail_number = 2
