Hi,
I'm working on the Pioneer Jupiter images and I'd like to share this with you. It's a rough cylindrical mosaic of Jupiter. Even working from imagens scanned from paper modern processing can make wonders to old data!

Yeah, I was about to say, "WHAT?" Doesn't your program know about "raw" formats?
I had assumed I was going to type a text file, then write a quick program that would turn that into a binary stream of bytes. (Then take a quick look in Paint Shop Pro loading it as a raw.) Heck, I bet you could load up a spreadsheet like Excel, fill in the cells with the numbers, and turn it into special 3D graph to view it directly. I KNOW you can do this in Mathcad from version 5 up: create a matrix, then display that matrix as a B/W contour plot. John D. |

Converting a simple text file containing numbers (e.g. one row for each image row) to something like PNG is trivial for me. In fact I already have a program I wrote for this purpose late last century when I was processing intensity profiles of Saturn's rings in text format.
Today I suddenly remembered that I have the Pioneer 11 Saturn special issue of JGR and it contains something interesting: Pages 5918-5919 contain a printed table of numbers for red and blue channel images of the rings. There is another smaller one (red channel only) on page 5920 showing the rings silhouetted against Saturn (Saturn's limb is also visible). I remember typing at least one of these into a computer ages ago but I cannot find it - I probably lost it ages ago when moving stuff between computers. I wonder if these are the images Ted has in mind. This appeared in JGR vol. 85, no. A11 (November 1, 1980). BTW there is a related thread here. Maybe these two threads should be merged... Despite the comments above on the good quality of scanned images there's another reason for wanting this data in digital format: Getting *all* of the Pioneer images (the majority hasn't appeared in print). I have all of the Voyager, Galileo and Cassini images and my collection of outer solar system spacecraft images isn't complete without the Pioneer images  .

I'll keep at it, but if someone want's to do it, at least here's part of it ;-) I'm typing colums 0 to 10, row by row (almost done) and then I'll move on to colums 10-20. If someone want's to start at the oposite end (colums 30 to 40) it would be a great help!!!
