VALD3 line lists include lines that are forbidden by quantum mechanical selection rules or lines that involve two-electron excitation (the so-called "autoionizing" lines). Such transitions are marked by a letter that follows the Accuracy field in the Long Format output. The table below explains the meaning of the letters:
