+We selected all the stream stellar particles within 3 kpc of the Sun from Robyn Sanderson's data set and applied the random errors expected for FGK dwarfs as estimated by [[http://adsabs.harvard.edu/abs/2015arXiv150803736R| Re Fiorentin et al. 2015]].

+Here, we present the resulting Lxy vs. Lz distribution of the "expected" local streams found using the "true" values (bottom panel),  the final Gaia catalog (middle panel), and the current ground based surveys (top panel).

-I use 50 randomly selected stars (without error) from a single stream (#41). I model the orbital energy distribution in the stream (without distinguishing leading and trailing streams) as a Gaussian distribution and run an emcee code to derive the posterior distribution of $(\log_{10} M/M_\odot, \log_{10} b/{\rm kpc})$.
