1. The first encounter (C3) occurred on 4 November 1996 at 11:47:09, the second (C9) occurred on 25 June 1997 at 13:47:50, and the third (C10) occurred on 17 September 1997 at 00:18:55, where the encounter times are expressed in Universal Time Coordinated (UTC) at the spacecraft, and the encounter designation Cn refers to an encounter with Callisto on the spacecraft's nth orbital revolution of Jupiter.

15. Undifferentiated models of Callisto involve transformations of ice to phases such as ice II, ice VI, and ice VIII at depth in the satellite [M. J. Lupo, Icarus 52, 40 (1982); J. Leliwa-Kopystynski, L. Makkonen, O. Erikoinen, K. J. Kossacki, Planet. Space Sci. 42, 545 (1994)]. Other phases of ice (ice III and ice V) may occur depending on the radial profiles of temperature and pressure in the model interiors. The depths of the ice phase changes also depend on the temperature and pressure profiles [G. Schubert, D. J. Stevenson, K. Ellsworth, Icarus 47, 46 (1981); G. Schubert, T. Spohn, R. T. Reynolds, in Satellites, J. A. Burns and M. S. Matthews, Eds. (Univ. of Arizona Press, Tucson, AZ, 1986), pp. 629-688].
