- matplotlib 
- pandas (v0.18)
- lmfit, for transit fitting ()

Installation Instructions

1. clone the git repo. Will create a </path/to/terra> directory

2. cd into target directory

   /global/homes/p/petigura/code_carver/terra
   

3. Build the cython and fortran extensions with make. At NERSC, there was a little difficulty getting the fortran and c libraries to compile. Here's what I had to do:

   module load gcc
   # This will compile the cython extensions but the -dynamic lookup won't pass to the gfort
   LDFLAGS="-L/global/homes/p/petigura/anaconda/lib" SOFLAGS="-fPIC -shared" make
   # Running it a second time will get the fortran code compiled
   make
   
   # the last compiled fortran code should look something like:
   /opt/gcc/4.9.2/bin/gfortran -Wall -g -Wall -g -shared
   

4. Add </path/to/terra> to $PYTHONPATH

5. Add </path/to/terra> /bin/ to $PATH

6. Test that everything is working by running the following test

   python -c "from terra import terra; terra.test_terra()"
