The Systemic GUI interface

Introduction

Systemic Console 2 is a new software package for fitting and analyzing a variety of exoplanetary data. It is a complete rewrite of the old Systemic Console. It consists of a fast, parallelized C library (which you can easily integrate into your own project), an R package providing a high-level interface to the library, and an easy-to-use  “studio” user interface for interactive use and plotting.

Systemic is an open-source project released under GPLv3. You can browse its source code on its GitHub page.

Features

  • Interactive fitting of radial velocity and transit timing data using a point-and-click interface or scripts;
  • Lomb-Scargle periodograms with bootstrapped false alarm probabilities;
  • Self-consistent integration using a builtin integrator (Runge-Kutta 8/9 or Bulirsch-Stoer) or a custom integrator;
  • Optimization using one of the Simplex, Levenberg-Marquardt, Simulated Annealing or Differential Evolution algorithms;
  • Error estimation using Bootstrap, Markov-Chain Monte Carlo, or custom routines;
  • Simple facilities for data input/output, manipulation and cleaning;
  • Dynamical integration with SWIFT’s RMVS algorithm;
  • And many more features (explore the menu of the Systemic user interface for pointers).
