Below are the final 143 da/a values with 1-sigma error bars derived in
Murphy, Flambaum, Webb, Lect. Notes Phys., 648, 131, 2004. Note that,
as per the discussion in that paper, the error bars for some absorbers
at high-z (z>1.8) have had added to them an additional error component
derived from the observed scatter in the da/a values for that subset
of absorbers. Otherwise, the error bars derive only from the photon
statistics of the absorption spectra.
