Jupiter's Synchrotron Radiation: an Intercomparison of Data, Models and 3-D Reconstruction Techniques
Imke de Pater (UCB), R.J. Sault (ATNF)
We present 3-D results of imaging experiments performed on data and
models of Jupiter's synchrotron radiation. The data have been obtained
at the VLA in 1994, and the models were derived such as to fit the
2-dimensional brightness distribution of the radio emision (see de
Pater et al., JGR, in press). We used both a backprojection technique
(described by de Pater et al., Icarus, in press) and a 3-D Fourier
Transform algorithm (Sault et al., Astron. Astrophys., in press;
Leblanc et al., 1997, Astron. Astrophys, 319, 274) to obtain
3-dimensional images of the data and the model. We will show a
comparison of the two techniques, and a comparison of the model and
data in 3-D. Even though the model images in 2-D matched the data very
well, there are some interesting differences in the 3-D images, which
yield useful information on the electron distribution and on
modifications of Connerney's
magnetic field model.
