Combining decidability paradigms for existential rules. Theory and Practice of Logic Programming - Corrigendum

Figure 3 was left out in the article (Gottlob et al. 2013). The figure that is given there as figure 3 should in fact be figure 4. Further, the reference to figure 3 on the 4th line of page 889 should be a reference to figure 4. The correct figure 3 (missing in the paper) is supplied below. We apologise for this error.
