This is the SEGUE data used in the Bovy et al. (2012, 2013) papers on the decomposition of the Milky Way disk in terms of mono-abundance stellar populations: The Spatial Structure of Mono-abundance Sub-populations of the Milky Way Disk, Bovy, Rix, Liu, et al. (2012) The Milky Way Has No Distinct Thick Disk, Bovy, Rix, & Hogg (2012) The Vertical Motions of Mono-abundance Sub-populations in the Milky Way Disk, Bovy, Rix, Hogg, et al. (2012) A Direct Dynamical Measurement of the Milky Way's Disk Surface Density Profile, Disk Scale Length, and Dark Matter Profile at 4 kpc ~ R ~ 9 kpc, Bovy & Rix (2013) This data can be used together with the code available here and here to reproduce the results in that paper. For completeness, similar data on K dwarfs in SEGUE is also included, but note that the selection function of these data is significantly more complicated than that of the G dwarf data. This dataset can almost entirely be reconstructed using the SQL queries given here on SDSS Sky Server, except for the [a/Fe] values from SDSS DR8, which were never made public. These [a/Fe] values are provided here solely for the purpose of reproducing the results from the above papers and should not be used for other purposes. Please contact the SEGUE team (Young-Sun Lee, Tim Beers, Connie Rockosi) if you want access to these data for other purposes.
