In the [[TJ-II:Shot_database|TJ-II database]], the raw data are called 'INTERI', 'INTERQ', and the processed data 'Densidad2_'.
In the [[TJ-II:Shot_database|TJ-II database]], the raw data are called 'INTERI', 'INTERQ', and the processed data 'Densidad2_' (units: 10<sup>19</sup> m<sup>-3</sup>).
The signal is less reliable for high densities (above 2-3 10<sup>19</sup> m<sup>-3</sup>) due to the cumulative effect of spurious phase jumps.
