Panel a: blueshifted component of the H2 emission in the K band in IRS 54 from the SINFONI 2014 data. Four spectral channels were averaged from 2.12087 μm (−125 km s−1) to 2.12160 μm (−22 km s−1). Panel b: redshifted component of the H2 emission in the K band in IRS 54 from the SINFONI 2014 data. Four spectral channels were averaged from 2.12185 μm (30 km s−1) to 2.12258 μm (134 km s−1). For reference, the centre blue contours represent the position of the continuum of the source taken at levels of 0.2, 0.4, 0.6 and 0.8 of the continuum flux.
