 Effective Collision Strengths
 From Hayes (J Phys B 25, 2649, 1992, same as DL/SCI/P802T, 1992),
 a close coupling calculation.

 Ionisation Potential
 Taken from Kelly (J Phys Chem Ref Data 16 Suppl No 1 1987)

 Energy Levels
 Taken from Edlen (Phys Scri 28, 483, 1983) for n=2 levels
 Taken from Kelly (see above) for n=3 levels
 (both these are as adopted by Hayes)

 A Values
 As given by Hayes, Model 2 (length) for allowed transitions from
 levels 1 and 2. For 1-2 the result of Dankwort and Trefftz (Astr. and
 Astro. 65, 93, 1978 is used. For 3-7, 3-8, 3-10, 3-13, 9-10 and 10-11
 the results of Hayes are used and for 4-8, 5-7 and 5-8 the results of
 Dankwort and Trefftz are used.
 A comparison of Hayes and Dankwort and Trefftz shows the following:
 Transition  Diff (%)
   1-3         0.94
   1-4         0
   1-5         0
   1-9        -9.7
   1-11       -0.2
   2-6         1.1
   3-7         2.4
   3-8        -1.3
