Map of n_H2 derived from the ¹²CO emission in the 3 to 10 km s^-1 velocity range (roughly equivalent to a distance range of 1 to 3 kpc) overlaid with contours from the 11 cm data (for levels 0.07, 0.095 and 0.12 Jy/beam) and selected objects (see Sect. 5). The Terzan 5 circle indicates the half-mass radius of the GC. Colour scale normalised by 10²⁰ cm^-2. The map was blanked where no value was available.
