  Collision strengths have been calculated in the close-coupling
  approximation using the B-spline Breit-Pauli R-matrix method.
  The effective collision strengths are tabulated for 1653 fine-structure
  transitions among the 58 levels at electron temperatures in the range
  from 500 to 100,000 K. The line strengths, oscillator strengths, and
  transition probabilities for all E1 transitions are tabulated.

  This data is the basis for CHIANTI but includes effective collision
  strengths for all transitions. Only electric dipole A-values are
  given (CHIANTI supplemented these with other sources). The numerical 
  data is taken from the tables in the online version of the paper at
  the ApJ website. Experimental energies from table 1 are used.
