Different maps of NGC 6845. Top left: false-color optical Gemini image. The white ellipse represents the region that follows circular motions in the velocity field (top right panel). Top right: Hα velocity field. Bottom left: modeled velocity field. Bottom right: residual velocity field, derived from the observed and modeled velocity field. The bar scale represents the velocities in km s⁻¹ of the residual map. The black box corresponds to the IFU/GMOS FoV, and the dashed black box corresponds to the area shown in Fig. 10.
