The density of neutral gas near comet Halley was measured by the Neutral Gas Experiment on the Vega 1 spacecraft. Plots of gas density vs. distance to the comet nucleus show an asymmetry between the inbound and the outbound legs of the spacecraft flyby. A multidimensional analysis is presented. It permits gas densities detected at distances between 8.9×103 and 7.2×104km to be mapped back to source regions on or near the comet nucleus, thus providing information on the spatio-temporal properties of the source of neutral gas in comet Halley. Sample results of the mapping-back process using an outflow velocity of 0.9 km s-1, scale lengths of 2.9×105km and 7.0×104km, and the faster rotation period of 2.09 days are presented.
