# Install CSPICE on your machine:
http://naif.jpl.nasa.gov/naif/toolkit_C.html
# Mac users can use MacPorts (port install cspice)

# Put the following files in your data directory:
# pck00010.tpc
# naif0012.tls
# de421.bsp
# You get these from here:
# http://naif.jpl.nasa.gov/naif/data_generic.html
# Go to the FTP site on that page
# The pck file is in the "pck" subdir
# The naif0010.tls file is in the "lsk" subdir
# The de421.bsp file is in the "spk/planets" subdir

# Edit the Makefile to point to the SPICE data directory you created above

### IMPORTANT!
Then, modify the fermikernel.tm file to point to the directory where the data files are installed
Also, modify FT2.setup to have the correct path name for the leapseconds file

# Get an FT2 file that you want to process

# Create FT2.in file 
python parseFT2.py <my_FT2_file>.fits

# Make Fermi-FT2.spk file from the FT2.in file
# On some platforms the command is "CSmkspk" instead
mkspk -setup FT2.setup

# You can now delete FT2.in if you want.  Only the Fermi-FT2.spk file is needed to run the code

# Update FT2 file with MOON columns
./moonpos <my_FT2_file>.fits

# Now, you can use the <my_FT2_file>.fits file just like your origninal FT2 file, but it has 2 extra columns
