Software Download:¶

• git access: https://git-cral.univ-lyon1.fr/lenstool/lenstool

• dependencies:
  - WCSTOOLS: [wcstools-3.8.4.tar.gz]
  - CFITSIO: [cfitsio3280.tar.gz] version must be at least 2.510.
  - GSL: [gsl-1.9.tar.gz]
  - PGPLOT (optional): [http://www.astro.caltech.edu/~tjp/pgplot/]

Note that you can also install CFITSIO, GSL and PGPLOT directly from your package manager. On Ubuntu, you can use the command apt-get from the command line.

• latest tarball source code (5.44Mb): lenstool-7.1.1.tar.gz

• older distributions
  - lenstool-6.8.1.tar.gz
  - lenstool_v6.7.1.tar.gz
  - lenstool-6.5.tar.gz

• compiled version
  - lenstool-7.1-macosx-10.13.zip
  - lenstool-7.1-linux64.zip
  - lenstool.maverick.6.8.zip

Please, contact Eric Jullo (eric.jullo AT lam.fr), if you want to provide a compiled version with another operating system. Compiled version have been compiled with option --disable-shared.

Software Install¶

cd lenstool
./configure
make

You can specify the location of cfitsio, wcslib, gsl and pgplot libraries using the configure options --with-X-include-path=DIR, --with-X-lib-path=DIR, where X stands for cfitsio, wcslib, gsl or pgplot. Since version 6.8, Histogram and Histogram2D tools are not anymore compiled by default. You need to specify the option --with-pgplot to compile them. These tools also depend on X11 development libraries and fortran compiler.

If you want to use the generalized NFW profile, you need to prepare the lenstool.tab lookup table with this command

make table 

In your .bashrc, you must add the following lines

export LENSTOOL_DIR=<path to the directory of lenstool package>
export PATH=$PATH:$LENSTOOL_DIR/src:$LENSTOOL_DIR/perl:$LENSTOOL_DIR/utils

or in your .cshrc,

setenv LENSTOOL_DIR <path to the directory of lenstool package>
setenv PATH $PATH:$LENSTOOL_DIR/src:$LENSTOOL_DIR/perl:$LENSTOOL_DIR/utils

Notes:

• For Mac Users, you need to previously install XCode and the Command Line Tools.
• Since 2015, there are 2 libraries available for wcs: wcslib and wcstools. You need to take wcstools.
• On Ubuntu, the package manager proposes libwcstools-dev. This package is not supported by Lenstool yet. Use the link above instead.
