I started a new thread with this info, so I am just going to merge it into this one. Here was my original post:
A whole slew of Huygens DISR views have been released on the Planetary Photojournal: http://photojournal.jpl.nasa.gov/new The big release is a movie showing the decent to the surface of Huygens using images from DISR, colorized by DISR spectrometer data. Views from different altitudes and projections were also released as well as views of the surface that have gone through more rigourous processing in the last few months. This data release by DISR, I believe, is part of, maybe not quite a special issue, but at least a series of articles on Titan coming very soon in a well known journal that puts new issues online on Thursdays... EDIT: Never mind. Completely unrelated. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

-------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

A high-resolution version of the movie (both silent and with sound), can be found at http://www.lpl.arizona.edu/DISR/Multimedia/Titan_Movies.htm. Please note that these movies are in Windows Media Video format.

What is interesting is that at last they suceeded in processing the complete image, including the one of the bottom camera, which was very hard because of uneven lighting. So we have the complete view now.

Interesting: in the descent movie you can see they used an elevation model to add relief. I'm surprised though by how much they have the light colored 'islands' standing out above the surrounding dark colored 'sea'. I had always pictured that being much flatter looking at the images.

"During its descent, the Descent Imager/Spectral Radiometer took 3,500 exposures. " ??? There were about 600 visual images in the raw image catalogue. If half the exposures were lost with channel A, does that mean that there were ~1000 spectral images? |

Most of those "exposures" were simply spectra -- not images of any sort. (I've even seen an exact count of them somewhere, although I can't remember where.) Don't forget that a single CCD array was used for all of DISR's data: images, spectra, and even photometry.
