It is shown that the detailed inter-relations of the 8.6 GHz mv in Stokes’ parameters I,Qand U of the quasar 0405-385, as quantified by their auto and cross correlations, can be successfullymodelled by interstellar scintil1ation (ISS) of a double source with two components separated byabout 10 micro-arc seconds. Though this is not a unique source model it confirms that ISS can explainquantitatively the rapid variations in both flux and linear polarization. Thus there is no evidence insupport of an intrinsic component in the IDV.
