Here's a magnified Gif version of the image, oriented as the printed data (planet limb/terminator? at top left) stretched and gamma corrected. Yes, I replaced the -1 values with averaged data, and did the same for a duplicated column :-) -------------------- _______________________

And here's the red rings image typed in Rest assured, I'll not type the blue one so soon so if someone wants to do it go ahead!!! -------------------- _______________________

Ted's probably already finished with this, but for completeness, here's my Excel version of the Blue-channel rings.
Note that there may be an offset from Helvick's version. Mine is 73 x 86 ("BU" across), and I included all the "0"s on all sides. (I think Helvick skipped the leftmost column of zeros.) Ringblue.xls ( 88K ) Number of downloads: 595 |

Mine is 73 x 86 ("BU" across), and I included all the "0"s on all sides. (I think Helvick skipped the leftmost column of zeros.) I see your point. The data for the red image seems to be offset horizontally by 1 pixel (to the right) when compared to your blue data. I've tried to bring them into line by adding an extra column of empty pixels to the blue data to bring them both to 73 pixels across. Anyway here's some png's: Red: Blue: and a color version using both of these and a synthetic green channel. |

Here's a quick processed version, with colour data merged to reduce noise. Colors were adjusted to a neutral yellow gray and saturation increased 50% to reveal hue variations.
Not bad at all Wish we had more old data to play, even if all of it had to be hand typed! -------------------- _______________________

I have done some work on it, and this is what I have come up with so far. It is an R-Synthetic Green-B color image merged with a super-resolution attempt with the two images. The F-Ring is artificially brightened.

Not bad at all Wish we had more old data to play, even if all of it had to be hand typed! I have several leads...If I come up with anything, I will post it. -------------------- |

Here are the best Pioneer views of the Galileans I could make. Europa and Callisto are entirely from scans. Ganymede is from a mix of scans and some limited digital information taken from a multitude of papers. Io is purely digital.

Is Pele's plume there real or did you add that to make me jump?

Yes, is this the discovery of a pre-discovery volcano image?

Would a plume even be detectable with exposures optimized for Io's dayside and with probably not-so-sensitive equipment? We're talking about the fuzz at the limb, right?
