At last I have the Pioneer 11 Io image in its raw form. Below to the left is my best processing of a scan in a book (I tweaked the terminator in that image because it was too problematic, which is the reason for the appearance of a different phase compared to the view on the right). To the right is a preliminary view generated from the raw data. It seems to be considerably more detailed. I plan to post an updated Pioneer 11 Io page on my site in the next day or two.

Ooh, beautiful blog. I'm gonna link to that.
(This is off topic, but Doug, it would be so nice for the people with sites if signature links worked again...) |

Sorry - I know what you mean - but it also means people can post stupidly long sigs with system configs, flash movies, big images etc - it's just all pointless. Doug |

Including images in sigs seems stupid and pointless. Including links in sigs seems like the only valid reason for sigs (I note one in your own sig). It's too bad if the forum software doesn't make a distinction, that seems like an obvious area for improvement.

What's the sub-spacecraft latitude and longitude of the Pioneer 11 image?

QUOTE (volcanopele @ Aug 19 2005, 05:48 PM) What's the sub-spacecraft latitude and longitude of the Pioneer 11 image? I am a bit confused, but I know the subspacecraft latitude was +60 and the degrees LCM was 184 (is this the longitude?). The phase angle is 67 degrees. -------------------- |

Assuming it is, I've attached a reprojection of a Galileo Io basemap using 60, 184 as the central latitude and longitude.

It is from a paper copy. The paper copy was the matrix of numbers that I manually converted to an image. On my site I describe how it was converted, and have lossless versions of the product.
I have rotated the image to the same angle as Jason's image, and have sized it down. The left image is Jason's, degraded to Pioneer size. The middle image is degraded a bit more. And on the right is from Pioneer. There are definitely some similar albedo paterns. The challenge would be to figure out what is artifact and what is change.
