Kinematic parameter deviations, Σ(λ_i, mc) and Σ(σ_i, mc) computed with respect to their mean values and normalized to the line-fitting errors derived using IDL for each individual spectrum. The mean deviations as well as their standard deviations are represented using dashed lines (light red for the Hα and cyan for the [NII] lines) and the shaded area in gray, respectively. Top panels: Hα results. Bottom panels: [NII] results.
