GISIC 2.0.5

Gaussian Inflection Spline Interpolation Continuum

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
