(1993), scaled to 56% (since they only measured rotation for 24 out of 43 cores). The dashed line represents the log-normal distributions of Case A ( $\overline{\log \beta} = -2.0$ , $\sigma_{\log \beta} = 1.2$ ) and the dash-dot line represents the log-normal distribution of Case B ( $\overline{\log \beta} = -2.2$ , $\sigma_{\log \beta} = 1.7$ ).

The four plotted points with error bars are observational values taken from Martín et al. (2000), FM92, DM91 and Shatsky & Tokovinin (2002). The hashed box represents the extrapolated multiplicty of PMS stars (Patience et al. 2002).

(2002), and the dashed line is their best fit to this distribution. The dotted line shows the predictions of our model for Case A ( $\overline{\log \beta} = -2.0$ and $\sigma_{\log \beta} = 1.2$ ) with parameters ${\cal N} = 5$ and $\sigma_{\log M} = 0.6$ . The peak and width of the model predictions are fairly close to the observations, with a similarly high overall multiplicity. b) The histogram shows the observed distribution of semi-major axes for binaries with G-dwarf primaries in the field from DM91, and the dashed line is their log-normal fit to this distribution. The dotted line shows the predictions of our model for Case B ( $\overline{\log \beta} = -2.2$ and $\sigma_{\log \beta} = 1.7$ ) with parameters ${\cal N} = 5$ and $\sigma_{\log M} = 0.6$ . The peak and width of the model predictions are similar to the observations, but the overall multiplicty is higher.
