Notes. Both results from the fitting method (pPXF) and the cross-correlation (CC) method are given. For the galaxy and the GCs, the S/N is measured in the wavelength range [6600 Å–6800 Å] in pix−1 (one pixel corresponds to a 1.25 Å channel). For the PNe the S/N is given for the [O III] λ5007 line. First (second) errors on the measured velocities represent statistical (systematic) uncertainties. The latter are the most extreme values obtained given a range of tested templates, background subtraction methods, and polynomial degrees of the Legendre function that was fitted to the continuum. For completeness, we augment the table with five GCs that were not covered by our MUSE observations, but for which velocities were reported by vD18 and for which we take the coordinates in Trujillo et al. (2019).
Observed in van Dokkum et al. (2018b) but no measured velocity due to too low S/N in their spectrum.
Re-measured value reported in van Dokkum et al. (2018d).
Globular cluster candidate reported in Trujillo et al. (2019).
