Replace this text \textbf{Figure 2.} The various derivatives calculated from the measured $P$ and $U$ in Figure 1 assuming that $c$ = 4.5 m/s (corresponding to the minimum seen in the next figure). The first differences $dP$ and $dU$ are calculated using a Savitzky-Golay filter  with your caption polynomial order 3 and window size 11. (upper left) - $dP(t)$, (lower left) - $\rho cdU(t)$, (upper right) - $dP_+(t)$, (lower right) - $dP_-(t)$. The separated differences $dP_\pm(t)$ are calculated using eq.(17). All of the differences have units of Pa.
