Gaussian Inflection Spline Interpolation Continuum
Project description
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.
Look how easy it is to use:
import GISIC
wave, norm_flux, continuum = GISIC.normalize(wave, flux, sigma=30)
Features
accomodates wide range of spectral resolutions via kernel width parameter
molecular band identification
Installation
pip install GISIC
