  67- 77  A11    ---     upper       Designation of upper level in combination

Note (1):
   The intensities are given first and are
   in table1: estimates of photographic blackening on a logarithmic scale
   in table2: marked E when from Edlen and Swings (1942) and
                     G when from Glad (1956)
   A roman figure following the intensity indicates an affected (a) line
   and blended (b) line of that iron spectrum. An arabian figure gives the
   multiplet number from Moore (1952).
Note (2):
   Predicted wavelengths are calculated from the adopted level energies
   in table 3 and table4. Observed are from:
   the present measurement in table1
   Edlen and Swings (1942) and Glad (1956) in table2
