Observed and calculated energies were in eV, but not flagged as such to
ADASDR post-processor which expects Ryd by default. So, a shift dE was
overshot by ~10dE. Affects low-T end of photoionized plasma range.

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.
