I have noticed that the January 1, 2007 Cassini PDS release is already available, see http://pds-imaging.jpl.nasa.gov/data/cassi...assini_orbiter/
I haven't downloaded all of the imaging data and I'm just beginning to digest what I already have but there are some beautiful images of Enceladus' plumes and satellite mutual events, images of the G and D rings and interesting images of Saturn's nightside and fairly good Iapetus images. Radar and VIMS is also available. All in all a nice 'Christmas gift' . |

Hm, taking Mimas as your 114 px baseline, that comes out to:
Mimas 114 Enceladus 140 Tethys 292 Dione 306 Rhea 417 Titan 1405 Iapetus 392 Assuming I'm not working with ridiculously antiquated figures here... |

In addition to size, I think the relative abundance of available images could be a consideration. In this light, it's good for Rhea to have a larger number as there are quite a few hi-res images available. On the other hand, Iapetus has a relative scarcity of images so I would go lower - back to the 100-200 pixel range. Titan makes sense to have a large threshold, partly as large images are needed to compensate for atmospheric blurring. -------------------- Steve [ my home page and planetary maps page ]
