Gaussian Smooth

Plugin Availability

The plugin will be visible when at least one compatible dataset is loaded.

Smooth spectra or cubes using a Gaussian kernel.

Description

The Gaussian Smooth plugin applies Gaussian smoothing to spectroscopic data, reducing noise while preserving overall spectral features. Smoothing can be applied along the spectral axis or spatial axes.

Key Features:

• Smooth 1D spectra or 3D cubes

• Configurable smoothing width (stddev)

• Spectral or spatial axis smoothing

• Uncertainty propagation

• Preview before applying
