tokens: Acknowledgments I thank Dustin Lang for providing the TGAS-matched APASS data, the 2016 NYC Gaia Sprint participants for stimulating discussions, and the anonymous referee for a helpful report. I also thank Maarten Breddels for finding and fixing a bug in Figs 2 and 3 . JB received support from the Natural Sciences and Engineering Research Council of Canada. JB also received partial support from an Alfred P. Sloan Fellowship and from the Simons Foundation. The MCMC analyses in this work were run using emcee (Foreman-Mackey etal. 2013 ). This project was developed in part at the 2016 NYC Gaia Sprint, hosted by the Center for Computational Astrophysics at the Simons Foundation in New York City. This work has made use of data from the European Space Agency (ESA) mission Gaia ( http://www.cosmos.esa.int/gaia ), processed by the Gaia Data Processing and Analysis Consortium (DPAC, http://www.cosmos.esa.int/web/gaia/dpac/consortium ). Funding for the DPAC has been provided by national institutions, in particular the institutions participating in the Gaia Multilateral Agreement. This research was made possible through the use of the APASS, funded by the Robert Martin Ayers Sciences Fund.
