For the record: from what I can see, the freshest orbital data is on this website. It is newer than the two main published papers from 2003 (Margot&Brown,Science 300,1939; Marchis et al,Icarus 165,112), and includes observations with the 8m VLT telescope which have far better resoultion than the earlier images. It appears to be maintained by the authors of the Icarus paper. Presumably this freshest calculation using best resolution data is the most accurate as well. Deuar 16:23, 5 June 2006 (UTC)
