How do you find the contributions per atom for calculating the reducible parts?

For example CO3-2 has pt. grp: D3h.

From the character tables-- the first row (unshifted atoms) is: 3,0,1,3,0,1. Second row (coefficients): 1,2,3,1,2,3 Third Row (contributions per atom): ?,?,?,?,?,?


The answer is 3,0,-1,1,0,3 but I can't find any hints on how this was obtained. Thanks so much for the help.

I'm afraid I don't quite understand what the question is.  Could you restate it?  Tell exactly what you've done and what you're having trouble with.
