SINFONI view of the H2 emission in NGC 3256, mostly covering the region surrounding the secondary (southern) nucleus. The primary and secondary nucleus are marked with an × and +, respectively, and are shown in more detail in Fig. 3. Top + middle: maps of the H2 flux (F), velocity of the emission-line peak (v) and velocity dispersion (σ = FWHM/ 2.35, with FWHM the full width at half the maximum intensity) of both the narrow- (top) and broad-component gas (middle). Velocities are with respect to z = 0.009354 as per Piqueras López et al. (2012a), which is the assumed systemic velocity of the secondary core (Sect. 1.1). Units are in × 10-17 erg s-1 cm-2 (F) and km s-1 (v and σ). Bottom: H2 emission-line profiles, plus continuum-subtracted 2-component Gaussian fit, in regions A, B and C. The spectra were extracted from a circular aperture of 13 spaxels of 0.125′′ × 0.125′′ each (i.e., roughly the size of the seeing disk), centered on the broad-component H2 features.
