Relative inclination of the discs in each multiple stellar system as a function of their projected separation. 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 labelled as UZ_Wab). In the other cases, the first two letters of the target name are labelled.
