 Oscillator strengths: 
     A values: computed from 'superstructure' using a 24
       configuration model of Fe XIII.
     comment: the model of Fe XIII included the following configurations:
       3s2 {3p2 3p3d 3d2}
       3s23p {4s 4p 4d 4f}
       3s3p2 {3d 4s 4p 4d 4f}
       3p3 {3d 4s 4p 4d}
       3s3d {4s 4p 4d 4f}
       3s {3p3 3d3 3p3d2}
     note: that level 18 is metastable, and can decay down to levels
       in the 3s3p^3 and 3s^23p3d configurations via electric quadrupole
       and magnetic dipole transitions. However, the strongest
       transitions are down to the ground configuration via two magnetic
       QUADRUPOLE transitions. These transitions are accurately known
       since the line strength hardly changes when extra configurations
       are added to the model.
