The (FONAC - Hic) and (FONAC - CMC11) differences of coordinates and proper motions were considered as orthogonal functions dependent on equatorial coordinates and magnitude of stars. After the systematic part of the expansions is taken into account the root-mean-square differences (FONAC - CMC11) are, on the average, 0.24'' in both coordinates for positions and 0.0050''/yr for proper motions. The similar estimate for the differences (FONAC - Hic) are 0.19'' and 0.0037''/yr. In view of the high accuracy of the HIPPARCOS catalogue, the latter quantities may characterize the random errors of the FONAC catalogue.
