29-30 August 2007 Icy Satellites (rev 49), Last stop on the road to Iapetus Options

[Exploitcorporati...]

CICLOPS' Rev 49 Looking Ahead page is up. Highlights include a fourth monthy Voyager-class encounter with Tethys with 500m resolution over Odysseus (finally!)
Detailed mosaics of Rhea's prominent ray crater and points west are on tap for Old Scabby's second closeup. This should be a really cool periapsis passage to tide us over until the 10th of September.

Hi all,

I've been working in IDL so I wrote a procedure to find how much of the line is black (or near black beyond a threshold), then take the average of the two surrounding lines. This is similar to one of Emily's methods I think.
I'll post it at this URL if you'd like to sort through the logic...

A good input threshold to use I find is around 27.

Updating this post about de-interlacing Cassini images, I can suggest trying to use the freeware software GDL to see if it is a viable alternative to the pricier IDL license.
