--- Table key -----------------------------------------------------------------------------------------
no. : composition point number;
T [K] : absolute temperature;
RH [%] : relative humidity in equilibrium with the liquid mixture (bulk conditions);
w(j) [-] : weight fraction (mass fraction) of species "j";
x_i(j) [-] : mole fraction of species "j", calculated on the basis of completely
dissociated inorganic ions; exception: the partial dissociation of bisulfate
(HSO4- <--> H+ + SO4--) is explicitely considered when present in the mixture;
m_i(j) [mol/kg] : molality of species "j" [mol(j)/(kg solvent mixture)], where "solvent mixture"
refers to the electrolyte-free mixture (water + organics);
a_coeff_x(j) [-] : activity coefficient of "j", defined on mole fraction basis;
a_coeff_m(j) [-] : activity coefficient of "j", defined on molality basis (used for inorg. ions)
with reference state of infinite dilution of "j" in pure water;
a_x(j) [-] : activity of "j", defined on mole fraction basis;
a_m(j) [-] : activity of "j", defined on molality basis (used for inorg. ions) with reference
state of infinite dilution of "j" in pure water;
flag : error/warning flag, a non-zero value (error/warning number) indicates that a
numerical issue or a warning occurred at this data point, suggesting evaluation
with caution (warnings) or exclusion (errors) of this data point.
