Description:
This data set is a critical compilation of data on atomic energy
levels for atoms and ions. For a number of the ions the levels have
been derived or recalculated. In addition to the level value in cm-1
and the parity, the J value and the configuration and term assignments
are listed if known. Leading percentages from the calculated
eigenvectors are tabulated wherever available.

Stage of ionization or spectrum number. The spectrum numbers are "1"
for Roman I (neutral atom), etc.
Note on P:
'@' = odd (italics in the publication)
blank = even
Note on Pre_E:
"[" = calculated value
Note on Suf_E:
"]" = calculated value
"?" = questionable
"*" = questionable
"+x"= uncertainty
Note on Pre_g, Suf_g:
See the printed documentation for details
Note to Code:
Percentage code (used to identify "Limit" records and "series" records
and to typeset leading percentages)
N=print the first percent
Q=print percent1, percent2,configuration2, term2
T=print everything
--------------------------------------------------------------------------------
There are seventeen fields for each level record. Each field with
character values is left-justified.
--------------------------------------------------------------------------------
Modifications made:
Excessive blanks between the fields were removed. The fields with
numeric values were right justified and prefix and suffix were
removed to separate columns. The formats for these fields were
changed accordingly.
