Figure 46: Regions in the (δ, log 10 x) plane corresponding to the classes of
perturbations listed in Table 26 for the QCD Lattice Fit case (cf. Bag Model
in Figure 45) – correct, except for A, B, and C (Section 7.3 gives the correct
graph). Here we are considering that the sound speed vanishes in the interval
t−
