Abundance distributions [Z/H]
Abundance distributions, [Z/H], which is measured logarithmically relative to solar values. The fainter GCs (lower line) show a significant bimodal distribution, with both groups having average abundance less than solar values. The brighter GCs (upper line, offset for clarity) are consistent with a single abundance distribution. Open circles show uncertainties of the histogram bins.
