tabulated long-range file generated by LAMMPS using reaxFF

Dear Lammps Users,

I want to use reaxFF force field in LAMMPS. Going through the LAMMPS manual and examples, I found out that LAMMPS makes it possible to tabulate the long-range interactions. To see how it works, I run the example provided for AuO system (you can see my input file in following). The problem is I am not able to interpret the information created by LAMMPS for tabulated interactions. I put also part of this information in following. I know that for each atom in the system it is computing certain properties but I just could not understand which properties have been computed here. I would be very thankful if someone could tell me that these columns refer to which quantities here.

From LAMMPS doc page, using tabulation for long-range interactions is invoked by the keyword tabulate_long_range:

tabulate_long_range: To improve performance, long range interactions can optionally be tabulated (0 means no tabulation). Value of this variable denotes the size of the long range interaction table. The range from 0 to long range cutoff (defined in the ffield file) is divided into tabulate_long_range points. Then at the start of simulation, we fill in the entries of the long range interaction table by computing the energies and forces resulting from van der Waals and Coulomb interactions between every possible atom type pairs present in the input system. During the simulation we consult to the long range interaction table to estimate the energy and forces between a pair of atoms. Linear interpolation is used for estimation. (default value = 0)

With this keyword, ReaxFF automatically switches to tabulated long range.
