The clustering of galaxies in the SDSS-III Baryon Oscillation
  Spectroscopic Survey: the low redshift sample
  We report on the small scale (0.5<r<40h^-1 Mpc) clustering of 78895 massive
(M*~10^11.3M_sun) galaxies at 0.2<z<0.4 from the first two years of data from
the Baryon Oscillation Spectroscopic Survey (BOSS), to be released as part of
SDSS Data Release 9 (DR9). We describe the sample selection, basic properties
of the galaxies, and caveats for working with the data. We calculate the real-
and redshift-space two-point correlation functions of these galaxies, fit these
measurements using Halo Occupation Distribution (HOD) modeling within dark
matter cosmological simulations, and estimate the errors using mock catalogs.
These galaxies lie in massive halos, with a mean halo mass of 5.2x10^13 h^-1
M_sun, a large scale bias of ~2.0, and a satellite fraction of 12+/-2%. Thus,
these galaxies occupy halos with average masses in between those of the higher
redshift BOSS CMASS sample and the original SDSS I/II LRG sample.
