Original paper: Zatsarinny et al A&A417, 1173 (2004).

The 2s2p^4 (autoionizing) levels were not counted as contributing to DR.

Partial database extended to higher-l for 2-3 core excitations (only). 
Totals refitted for consistancy, <~ 5% change at high-T peak (less at lower T).

The total DR rate coefficients from the adf09 files of Zatsarinny et al
have been (re-)fitted. The original fits published by Zatsarinny et al were
to DR totals generated by processing the AUTOSTRUCTURE rates thru the
(MDRCS12) code which is used to compare with cooler measurements, and
which bins resonance energies. This is inaccurate at low-T (temperatures
comparable with the bin width). ADASDR, which produces the adf09 files,
works with exact resonance energies and so, in principle is more accurate
at low-T. Of course, the theoretical uncertainty of near threshold resonance
positions is "large" anyway. The differences between the two sets of
results could be viewed as a measure of theoretical uncertainty.
