The DISR team has officially released two of their mosaics, one showing the surface as if through a fish-eye lens and the other a map projected image showing features very close to the Huygens landing site. These mosaics were released earlier on the DISR website, but I guess they have taken a while to show up on the Cassini site. A few items of note about these mosaics. One is the direction of north, it has changed. This change makes it very difficult to reconcile with known features in the region, based on ISS and VIMS data.
The DISR team has also removed three mosaics released a few weeks ago from their website. I have saved them so you should still be able to access them from their post earlier this month.
