Gaussian Inflection Spline Interpolation Continuum
Project description
Gaussian Inflection Spline Interpolation Continuum (GISIC)
GISIC is a python package for normalization of astronomical spectra. It is designed to accommodate spectra with heavy molecular features due to high elemental abundance enhancements. GISIC performs a gaussian smoothing of the flux array, and identifies molecular bands based on a numerical gradient. Continuum points are then interpolated with a cubic spline.
