Notes. For D2, D23, and D3.1 we can extract these values directly from the spectroscopic analysis of the SINFONI data cubes. The spectroscopic information for D3 in 2008 are extracted from Meyer et al. (2014). We determine an uncertainty of 0.0005 μm. This results in a velocity of ∼36 km s−1 for the HeI and Brγ emission line.
