    • The majority of the 124 images were acquired in a special mode (2 X 2 pixel summation and a fast 2.6-s readout time) designed to minimize radiation noise. We expected the radiation noise to be severe in images acquired close to lo, but the image quality proved much better than expected. Unfortunately, the summation mode, which worked correctly through orbit C21, produced garbled images in 124. Many of the images were reconstructed with an innovative algorithm devised at the Jet Propulsion Laboratory (JPL) with the LabVIEW software from National Instruments (Austin, TX). However, the photometry remains severely compromised, eliminating useful color data, and parts of some images are completely unrecoverable. Full-resolution imaging modes (no pixel summing) worked correctly, but only a few partial (top one-third) frames were acquired in 124 while dose to lo. 125 and subsequent encounters were replanned to acquire only full-resolution images.

    • Plumes have given names only (such as "Pele"), whereas surface features are called a patera (irregular or complex depression), fluctus (flow), mons (mountain), mensa (mesa), planum (plateau), or catena (chain). Most volcanic centers include several features, so in practice we often drop the feature name and refer to the entire complex by its given name.

    • The compressive stress induced by globally uniform subsidence exceeds 1 kbar at a depth of 2.5 km. For comparison, the stresses induced by tides are expected to be between 2 and 6 bar.
