Angular momentum Lz as a function of metallicity [Fe/H]. Stars with ages below 8 Gyr are shown in a blue density plot and those with ages above 10 Gyr as red dots. For both sets, mean angular momenta have been calculated in 0.25 dex steps in [Fe/H] for bins with more than 50 entries and are shown with mean [Fe/H] error and a combination of LZ uncertainty and standard deviation of the mean Lz as error bars. The solar angular momentum is indicated with a dashed line.
