[gmx-users] Label of the atoms in ffoplsaabon.itp

[Eudes Fileti]

Dear Gmx users:
I am a new user and I have some questions
Somebody could say me what it means the index at atoms in the
ffoplsaabon.itp file (a fragment of file
is gave bellow).
Some are obvious (OH, is oxygen bonden to hydrogen and HO is a hydrogen
bonded to oxygen)
but definitively I dont know what type of bond makes the carbon atoms like
C_2, C_3 or C *.
I cant find this issue at manual so forgive me for the basic question.

Thank you
eef
