Maps of the fitted J = 4−3 12CO (left panel) and J = 1−0 [CI] line (middle panel) integrated main-beam brightness temperatures towards the center of Cen A. The fitted maps are almosat completely insensitive to the absorption against the continuum nucleus that would otherwise depress the line fluxes at the center. Contour values are in steps of 6 K km s-1 for [CI] and 5 K km s-1 for CO and peak at 110 K km s-1 and 77 K km s-1, respectively (the color wedge is in units of = 0.6 Tmb). The [CI]/CO ratio map (right panel) has contours at intervals of 0.15 which clearly reveal the outline of the CND and its northeastern extension.
