Fitting Methods for Baryon Acoustic Oscillations in the Lyman-{\alpha}
  Forest Fluctuations in BOSS Data Release 9
  We describe fitting methods developed to analyze fluctuations in the
Lyman-{\alpha} forest and measure the parameters of baryon acoustic
oscillations (BAO). We apply our methods to BOSS Data Release 9. Our method is
based on models of the three-dimensional correlation function in physical
coordinate space, and includes the effects of redshift-space distortions,
anisotropic non-linear broadening, and broadband distortions. We allow for
independent scale factors along and perpendicular to the line of sight to
minimize the dependence on our assumed fiducial cosmology and to obtain
separate measurements of the BAO angular and relative velocity scales. Our
fitting software and the input files needed to reproduce our main BOSS Data
Release 9 results are publicly available.
