Abstract:

It is shown that the detailed inter-relations of the 8.6 GHz IDV in Stokes' parameters I, Q and U of the quasar 0405–385, as quantified by their auto and cross correlations, can be successfully modelled by interstellar scintillation (ISS) of a double source with two components separated by about 10 micro-arcseconds. Though this is not a unique source model it confirms that ISS can explain quantitatively the rapid variations in both flux and linear polarization. Thus there is no evidence in support of an intrinsic component in the IDV.
