Fig. 3. 2D radiation measured by bolometer (right) and CIII radiation from Tangential TV (left).

Here, a.u. means arbitrary units. Both show the radiation peaks near the X-point during full detachment (b, c) with respect to the attachment (a) whose radiation peaks almost at the divertor plates. Note that the reconstructed bolometer radiation near the lower divertor target has a large uncertainty since several lower bolometer chords are cut-off by the shelf tiles. N₂ puffing locations are shown as the purple arrows.
