1. The first line of each subset corresponds to the LS transition followed by the fine structure components. The letter prefix designation of the transitional states in the table corresponds to their energy positions, as explained in Table 3. The energy unit for the individual states and transition for the LS multiplets are in Rydberg. The energies are absolute and negative signs are omitted for convenience. However, for the fine structure transitions, the energies of the initial and final fine structure levels are in unit of cm^-1, while the transitional energy differences are in {AA} unit. The A-values are in s-1.
2. An asterisk (*) below an LS state indicates an incomplete set of observed energy levels, and an asterisk for the transitional energy indicates that one or both the levels are missing from the observed energy set.
3. Observed energies are used for all transitions in LS multiplets whenever available. An * between Ei and Ef values of the LS terms indicates calculated energies are used
4. An * for the energies of the two transitional fs levels means that one of the levels has not been observed. Hence the fs f- and a-values are obtained from calculated energies.
5. An * below the arrow of a transition indicates that the calculated transition was in reversed order.
6. An * on the left of a fine structure transition means that the low and the high energy levels belong to the higher and lower LS terms respectively. --------------------------------------------------------------------------------
