Abstract
We present a new 180th degree and order model of the Venus gravity fie ld directly derived from line of sight Magellan residual Doppler data instead of usual line of sight residual acceleration data. We discuss the influence of the a priori covariance matrices on the deconvolution process, and compare our results with previous solutions.
