In this paper four methods of the representing RSC systematic differences have been examined by comparison of the residuals of the radio source positions between each pair of individual catalogues. Eight radio source catalogues, and the latest ICRF realization, ICRF-Ext.2, were used for comparison. After selection of the best method how representing differences representation we compute the systematic differences between each individual catalogue and the ICRF. Then, these differences were used in the procedure of construction of the combined radio source catalogue. In results, representation of the systematic differences between RSC with Legendre-Fourier functions is proven to be the most accurate method. Using this method, two combined rad...
