I'd like to have access to the datafile of the electrical output of the RTG (Radioisotope Thermoelectric Generator) of the Pioneer's and Cassini missions, as can be seen in the figures 1 of the papers of Anderson,2002 and Peter S. Cooper, publ 2009.
I know that I can grab the aprox values directly from the published graphs with the help of software, but accessing the original data is better. I g-searched but I did not found them. Can someone give advice, pls?
The question is specific but the answers can say more about the difficulties and solutions of accessing scientific data.
