I am wondering if the use of "are" in the last subordinate sentence is correct. It makes sense that 'are' refers to 'nodal cover depths' while I think the correct antecedent is the number defined as nodal cover depths.
"Finally, figures 12 and 13 show the characteristics of the optimal solution obtained for test examples I and II, respectively, using CABAC in which the number in parentheses 'are' nodal cover depths."
