 # Si and C mixture, parameterized for Tersoff potential
 # this file is from Rutuparna.Narulkar @ okstate.edu
 # values are from Phys Rev B, 39, 5566-5568 (1989)
+# and errata (PRB 41, 3248)
 
 # Tersoff parameters for various elements and mixtures
 # multiple entries can be added to this file, LAMMPS reads the ones it needs
 # these entries are in LAMMPS "metal" units:
 #   A,B = eV; lambda1,lambda2,lambda3 = 1/Angstroms; R,D = Angstroms
 #   other quantities are unitless
 
 # format of a single entry (one or more lines):
 #   element 1, element 2, element 3,
 #               m, gamma, lambda3, c, d, costheta0, n,
 #               beta, lambda2, B, R, D, lambda1, A
