Those three tables define the actual AFR when in closed loop. The values are compared against the O2 sensor to move the integrator.

Up in the sticky's, in the Tuning Guide Book, under the '8063/'7747/'8746 ECM section. There is a paper on 747 Fueling. Even though it is a different maskId the principle is the same.
