The i-band image (left panel, scale in ADU in the right), the velocity field (central panel, scale in km s^-1 in the right), and the velocity dispersion map (right panel, scale in km s^-1 in the right) of the MASSIV source 020294045 (major merger). On each map, North is up and East is left. The level contours mark the isophotes of the two components obtained with GALFIT in the i-band image. The principal galaxy (red/white) is the one closer to the kinematical centre of the system and sets the origin in right ascension (α) and declination (δ), while the companion (blue/black) is the secondary component. The outer contour marks the 3.43 ADU (7σ_sky) isophote. The next contours mark brighter isophotes in 1.96 ADU (4σ_sky) steps. The luminosity difference between both components in the i band, Δm_i, as well as the CFHTLS exposure time, t_exp, are shown in the left panel. The redshift of the source and the on-source SINFONI exposure time, t_SINFONI, are shown in the central panel. (A colour version of this plot is available at the electronic edition.)
