Built-in line-shape helpers

This example shows the direct top-level helpers for generating common 1D profiles without instantiating fitting models explicitly.

import spectrochempy as scp

Build a shared abscissa and a few synthetic profiles.

x = scp.linspace(-4.0, 4.0, 400)

profiles = [
    scp.gaussian(x, ampl=1.0, pos=-1.5, width=0.9),
    scp.lorentzian(x, ampl=1.0, pos=0.0, width=0.8),
    scp.voigt(x, ampl=1.0, pos=1.5, width=1.0, ratio=0.5),
    scp.asymmetricvoigt(x, ampl=1.0, pos=2.5, width=1.2, ratio=0.4, asym=0.25),
    scp.sigmoid(x, ampl=1.0, pos=-0.5, asym=6.0),
]

Stack them as columns to compare the available shapes side by side.

shapes = scp.stack(profiles, axis=1)
shapes.y = scp.Coord(
    labels=["gaussian", "lorentzian", "voigt", "asym. voigt", "sigmoid"]
)

_ = shapes.plot(legend=shapes.y.labels, colormap=None)
