a) Continuum-subtracted spectral map of [OI]_63μm line in G5.89–0.39. The velocity range shown in the spectra ranges from −60 km s^-1 to +100 km s^-1. The temperature scale ranges from −10 K to + 20 K. b) Map of the continuum emission at 63 μm. Red and blue contours represent the integrated red- and blue-shifted intensity of the [OI]_63μm line. For the continuum emission and for the red- and blue-shifted integrated intensities levels are 50% of the peak intensity (9.0 K for the continuum, 187.5 K km s^-1 for the red wing, 422.0 K km s^-1 for the blue wing) in steps of 10%. The star indicates the position of Feldt’s star, the cross the peak of the SOFIA 63 μm continuum emission, the triangles are the peaks of the red- and blue-shifted [OI]_63μm emission (Table 2). The solid and dashed circles represent the 14.̋5 beam of the CO(16–15) data and the 11.̋6 beam of the OH ground-state observations. In both panels the centre position is , .
