| This plot was obtained
during standard procedure of INTERBALL AP attitude data treatment. The
main interest is that almost all kind of external influences to parameters
of motion (eclipse, normalization, ROS) are presented in the one time interval.
Three upper panels illustrate the spin velocity, the angle between kinetic moment and sun direction, and the nutation.All external events are represented on the lowest panel as blue, green and yellow columns. Note that the nutation (second lower panel with cyan colored plot) changed each time after eclipse (green columns). However, we observed both increase and decrease of nutation following eclipse.
