Fitting methods for baryon acoustic oscillations in the Lyman-
Author
Abstract
We describe tting methods developed to analyze
uctuations in the Lyman-
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 e ects 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 ducial cosmology and to obtain separate measurements of the BAO angular
and relative velocity scales. Our tting software and the input les needed to reproduce our
main BOSS Data Release 9 results are publicly available.
