Remove Background
=================

This example removes a constant background from a dataset.

.. GENERATED FROM PYTHON SOURCE LINES 9-10

Load the data

    import lumispy as lum
    import matplotlib.pyplot as plt

    cl1 = lum.data.asymmetric_peak_map()

Now we remove the background and display the data

If the parameter ``signal_range`` is not given, it can be selected interactively, see :py:meth:`hyperspy.api.signals.Signal1D.remove_background`.
