Ring diagrams are used to study the structure and dynamics of the near-surface layers of the Sun. The parameters of primary interest are frequencies and velocities in both the zonal and merridional direction as a function of wavenumber and of radial order n. These parameters are recovered by fitting a model of the spectral profile to three-dimensional power spectra of small regions of the Sun. In this work, we examine the systematic differences between fits assuming an asymmetric profile and fits assuming a symmetric profile. We also explore the coupling between the parameters of interest and certain secondary parameters such as amplitude, width, and asymmetry.
