in the following ions can be obtained from the anonymous account
in the Astronomy Department of the Ohio State University:
Fe II, Fe III, Si I, Si II

The f-files in the anonymous account are:
1. i) File "fjj.fe2" contains the f-, S, and A-values for fine structure
transitions in Fe II. The compressed files are: "fjj.fe2.gz",
"fjj.fe2.Z". Ref. S. N. Nahar, Astron. Astrophys. 293, 967 (1995).
[21,589 fine structure transitions. ]
ii) File "fjj.fe2.cal.gz" contains the f-, S, and A-values for fine
structure transitions in Fe II that are not included in the above
file "fjj.fe2". The transition energies in this file are the
calculated ones. [136,330 fine structure transitions. ]
The two files together complete the set of 157,919 transitions.
2. i) File "fjj.fe3.gz" contains the f-, S, and A-values for fine
structure transitions in Fe III. Ref. Sultana N. Nahar and Anil K.
Pradhan, Astron. Astrophys. Suppl. 119, 509 (1996).
[ 9797 fine structure transitions. ]
ii) File "fjj.fe3.cal.gz" contains the f-, S, and A-values for fine
structure transitions in Fe III that are not included in the above
file "fjj.fe3". The transition energies in this file are the
calculated ones. [124,334 fine structure transitions. ]
The two files together complete the set of 134,128 transitions.
