Parameter maps from spatially resolved spectroscopy of Vela, using the 2TNT model. We display the distribution of the following physical quantities: absorption column density N_H, mean temperature kT_mean, total electron density , relative abundances of O, Ne, Mg, Fe, normalized to solar values, of the thermal components, as well as spectral index Г and surface brightness Σ_Г in the 1.0–5.0 keV range of the nonthermal component. To provide a rough estimate of the typical noise level, the upper left corner of each panel indicates the median uncertainty for the respective parameter across all bins. The gray contours reflect the broad-band count rate of Vela, and are identical to those displayed in Fig. 1. The green polygons mark the two regions whose spectra are displayed in Fig. 4, and the green + sign marks the position of the Vela pulsar.
