Introduction

gal1d is a python package for analysing volume or surface density (luminosity) profiles and fitting them with theoretical profiles

Installation

git clone https://github.com/wx-ys/gal1d.git

Install this in editable mode.

cd gal1d
pip install -e .

See example for usage,

Profiles

analysis a single theoretical profile or a combination of the addition of some of these profiles.

  • NFWProfile: a Navarro-Frenk-White (NFW) profile
  • GNFWProfile: a generalized NFW profile profile (Kravtsov 1998)
  • DoublePowerLawProfile: a 'broken' or double power-law profile (Hernquist 1990; Zhao 1996)
  • EinastoProfile: an Einasto profile (Einasto 1965, 1969)
  • SersicProfile: a Sersic profile (Sérsic 1963, 1968)
  • ExponentialProfile: an exponential profile
  • CoreSersicProfile: a core-Sersic profile (Graham et al. 2003; Trujillo et al. 2004)
