Focus bursters—summary. The table summarizes the results for the deg. TB singularity, focus case. Rows represent the four onset bifurcations, columns the four offset bifurcations. For each class we distinguish (sub-columns) the cases in which the equations of the unfolding are used with time forward or time reversed. With the sub-rows we distinguish the existence of hysteresis-loop (h-l) or slow-wave (s-w) classes. In gray we mark the existence of a given class. The number 2 inside a cell indicates that for that class two realizations in different regions of the unfolding are possible. Overall the highest amount of classes is obtained in the time reversed case: all the sixteen slow-wave are in there and seven hysteresis-loop ones (one of them, c2, with two realizations)
