A gravitational lensing software for modeling mass distribution of galaxies and clusters (strong and weak regime).
LENSTOOL package contains a C library and several executables for creating, and post-processing gravitational lensing models. LENSTOOL lens model, processing steps, and input data are listed in an ASCII parameter file. The lenstool executable parses this file and performs the successive requested processing steps.

LENSTOOL package contains a C library and several executables for creating, and post-processing gravitational lensing models. LENSTOOL lens model, processing steps, and input data are listed in an ASCII parameter file. The lenstool executable parses this file and performs the successive requested processing steps. Perl scripts provided in the package allow to visualize output results in the graphical interface DS9 provided by Smithsonian Astrophysical Observatory (SAO). In case of MCMC model optimization, MCMC samples are delivered in an output ASCII file. MCMC samples can be post-processed by several additional executables provided in the package.
To install lenstool, run the following command in macOS terminal (Applications->Utilities->Terminal)
sudo port install lenstool
To see what files were installed by lenstool, run:
port contents lenstool
To later upgrade lenstool, run:
sudo port selfupdate && sudo port upgrade lenstool
