The quantities stored in this IDS include electron and ion temperatures, densities of electrons, several ion species and several neutral species, loop voltage, and plasma current. Although all these quantities are represented by single values, most of them are stored as 1D-profiles on the formal grid consisting of a single point. When the ion and neutral densities are recovered from the IDS, the species are selected in the array of structures by their labels (not by their places in the array). This is done to permit more flexibility if the set of the ions simulated by the code changes. At present, the storage of ion quantities in the IDS is organized as follows:
