Note (1): The element and ionisation stage are packed into one parameter given by Z + (Z-N)*0.01 where Z is the atomic number of the element, and N is the total number of electrons. Note (2): A value of -1.0 indicates that the data was computed directly and not interpolated from the grids. This occurs for all lines of singly ionised species and a few important neutral species lines where the states lie just off the grid. Note (3): The atomic unit of cross-section is a02, Bohr radius squared (the Bohr radius is the constant a0 = ε0 h2/(π m e2) from Permittivity, Planck, electron mass and charge constants)
