Inferred temperature from a non-LTE inversion. Temperature slices from the inversion are shown in two columns at quiescent (right) and flash (left) phases at several optical-depth log τ₅₀₀ = −4.2, − 2, − 0.5 respectively from top to bottom. Note that we have performed a depth average of 0.5 dex, centered at those heights. The minor tick-mark separation is . The white cross marks the center of the patch of which the temperature and velocity stratifications are shown in Fig. 5
