\caption{Entropy and pressure fluctuations
around the mean sample trend. Results of the spectral analysis
using two different masks are shown. The $I$-$T$ is the mask based on
cross-sections of the isothermal and isodensity regions. The $S$-$P$ is the mask
based on the cross-sections of the isentropic and isobaric regions.}
