modification for "plus" shaped fin configuration

[saumya221]

I am experimenting with a modified version of eca_a9, where among other things, the fins are placed in "+" shape in stead of "X" shape. I have tried to change the roll map, pitch map and yaw map..but I am not able to get any orientation control through auv_geometric_tracking_controller. Can anyone suggest what the modifications to be there for "+" shaped fin configuration?
