# fcof is the weighing factor for each method of fitting
# 1st value is for least squared difference of wavefunction shape
# 2nd value is for the lsd of derivative of wavefunction
# 3rd value is for lsd of the wavefunction shape weighed by

# 1st number is angular momentum l of numerical wavefunction
# 2nd number is angular momentum of gaussian
# 3rd is the number of gaussians
