Due to an oversight on the authors’ part, figure 27(b) in our original manuscript (Podvin & Fraigneau Reference Podvin and Fraigneau2024) is incorrect. The correct figure should read:

Figure 27. Predicted frequencies of the dominant POD amplitudes with the linear autonomous model (LM) for two different truncations
$N_T=6$
(black lines) and
$N_T=10$
(red lines):
$|\hat {a}_{0}^n|^2$
for
$n \in \{1, \ldots, 6\}$
$|\hat {a}_{1}^n|^2$
$n \in \{1, \ldots, 6\}$
.
