Channel definitions used by the Juelich group
The following is a sample output from using the 3nf_read.py script:
- The script reads a 3bME file from Epelbaum and prints some information.
- Note in particular the channel definitions and numbering.
- This particular example is the J=1/2, T=1/2, pi=+ channel (v1p5.chiral-lec-c-laminf-p16n5-1-v4-1+P.T=1_2.form)
- Note that there is a two-body cutoff j_{NN} <=5
