Difference between AIREBO and REBO

Hi folks,

I know there are bunch of discussions on this issue. Since it is not
REBO when the functions of LJ and Torsion parts of AIREBO are turned
off (the bond length of C-C in graphite is still 1.396 nm as the two
parts turned off, however, it's 1.42 nm with REBO), I wonder if anyone
can point out how can we use REBO in Lammps. Is there anyway we can
use REBO by modifing the AIREBO code? Thanks!
