Fig. 4.
Spatial trends of the galactocentric radial velocity dispersion for the MP (left) and MR (right) component, respectively. The maps are the results of a linear interpolation between the measured value of the σ for the two components in the 26 GIBS fields. The maps are symmetric in longitude and latitude by construction, and have been normalized to the same color scale. Contours show the value of σ, in km s−1, in step of 10.
