Compiled data for bubble rebound energies for cases A–I. For each data set considered, the mean rebound energy is plotted as a circle or a triangle, while the vertical bar represents the mean ± one standard deviation. Note that these vertical bars thus have a different meaning from those in Fig. 5, which denote confidence intervals. For each “case,” two data sets are plotted: collapses with no visible jet on the left (open circles) and all collapses on the right (filled triangles). The number above each data set is the number of observations. Accordingly, for case A conditions, there were 12 observed collapses with no visible jet out of 31 total collapses.
