The Method

First, we normalize with the Continuum task from the stsdas package.

Then we select the points where to fit the gaussian.

continuum ../*_* @norm.txt

Then I call a Python script and do the fit using pyraf. The script can be found in the GitHub Repo MUSE Data Reduction 2016. In the folder misc/Spectra/fitting.
