Abstract
Kalberla et al. used HI4PI data to analyze velocity and density fluctuations in the interstellar medium (ISM). They applied the Yuen et al. (2021) velocity decomposition algorithm (VDA) for separating such fluctuations in the position-position-velocity (PPV) space. In the first version of this manuscript they came to the conclusion that velocity and density fields are statistically correlated. Yuen et al. (2021) tried to reproduce these results and pointed to a likely mistake in the VDA expression that was used. We confirm that there was such a software problem. The statement that VDA derived density and velocity fields from HI4PI are anti-correlated needs to be withdrawn. Correct is that these density and velocity fields are uncorrelated. In turn major parts of the conclusions in the first version of this manuscript, based on an erroneous correlation, are invalid. The submission to A&A was withdrawn on 24 February 2022.
