Compressibilities of magma (\(\kappa _\text{m}\)), liquid (\(\kappa _\text{l}\)), crystals (\(\kappa _\text{c}\)), and liquid + crystals (\(\kappa _\text{lc}\)) as a function of the initial H\(_2\)O content (\(n_\mathrm {H_{2}O}^0\)) and varying initial CO\(_2\) contents (\(n_\mathrm {CO_{2}}^0\)). Results for (a) \(n_\mathrm {CO_{2}}^0 = 0\) wt%; and (b) \(n_\mathrm {CO_{2}}^0 = 1.4\) wt%. The pressure (p) is set as 245 MPa
