First coordination number

Dear Lammps users.
Hi, how do I calculate theFirst coordination number in lammps? I used the command “compute coord/atom” in the lammps manual and got the result file, but I’m not sure what each column means? I hope you can answer this question.
Here rdf1_solid.txt is the file obtained by calculating the radial distribution function; stab1_1000.txt is the file obtained by calculating the First coordination number.

rdf1_solid.txt (13.9 KB)
stab1_1000.txt (357.6 KB)

What the output contains should also be discussed in the manual for either command.

Thank you for your reply, the problem has been resolved.
