Left panel: velocity broadening at 2σ upper limits for the (−1.7′, +1.7′) and the (−0.4′, +0.4′) regions at comparison. The spatial broadening was removed through the MOS 1 surface brightness profiles. Right panel: (−0.4′, +0.4′) velocity 2σ upper limits compared with those estimated in the same region but with the variable best-fit, spatial broadening (scale parameter, s, is free in the lpro component, see Sect. 4.2 and Table A.1).
