Comparison between the PAs (top) and inclination (bottom) for the discs around the primary and the secondary in each multiple stellar system where both discs are detected and resolved. We considered the UZ Tau system as two binaries, comparing UZ Tau E parameters with UZ Tau Wab parameters (comparison labeled as UZ_Wa and UZ_Wb for the two UZ Tau Wab discs) and UZ Tau Wa parameters with UZ Tau Wb parameters (comparison labeled as UZ_Wab). In the other cases, the first two letters of the target name are labelled.
