If you have Homebrew, you can easily install SALT2 on OS X by doing: brew install salt
. Once done, the installation can be tested with: brew test -v salt
.
The current formula installs SALT2.4, which is the code version used for the Joint SDSS/SNLS Lightcurve Analysis. If needed, you should also install the gfortran
dependency. The data directory (the SALTPATH
) will be created in the Cellar
, with the SALT model, instrument and magnitude system files:
$ tree -L 2 `brew --prefix salt`/data
/usr/local/opt/salt/data

You can add your own instrument files into the same directory and update the fitmodel.card
