This is a supernova-centric grid based fitter for measuring the cosmological parameters, specifically for fitting the dark energy equation of state.
###Installation
Installation is via the standard UNIX configure and
make. pofd_affine depends on the following packages:
- cfitsio
- The GNU scientific library
- It can benefit significantly from LAPACK/BLAS libraries,
either ATLAS or
the Intel MKL;
on OSX there is also support for the built in accelerate libraries.
It may be necessary to tell configure where to look for these
libraries -- see
configure --help.
Note that if you got this from github rather than downloading
a .tgz, you may need to do something like autoreconf -fvi before
building to set up the build environment.
Fuller documentation is provided using Doxygen. This can be generated using
make docs
The resulting documentation describes the format of the input file.
The most interesting branch -- which will never be merged -- is a branch to handle the galaxy dependent offset in the absolute magnitude of Type Ia SNe as described in Sullivan et al. (2010). This is the twoscripm branch, and was the one actually used in the SNLS 3rd year analyses.
- This code is based on one I wrote for my PhD thesis, as presented in Conley et al. 2006
- It was used in the SNLS 3rd year analysis in both Conley et al. 2011 and Sullivan et al. 2011
- It was also used in the ESSENCE results, as described in Wood-Vasey et al. (2007)
