N1  - I thank the DESY Directorate and the IT-division for their constant support. Iexpress my gratitude for the fruitful discussions with the GRAVI-group at DESY, G. Schierholz, U. Martyn, and K. Schmidt-Hoberg. I thank the SPARC-group forproviding the astronomical data. This Preprint is based on my personal reasearch results. It is not the result of a group activity (P. Steffen)
AB  - The factorization of the radial distance of different galaxies into a galaxy dependent factor and a dark matter dependent factor is presented. Using the dark matter dependent factor, dark matter properties can be investigated independent of the mass and size of the different galaxies. Details are presented using the publicly available measurements of 2693 stellar objects of 153 different galaxies of the SPARC-group [3]. The results are unified radial distributions of dark matter properties independent of differences between galaxies. Distributions of velocity, acceleration, mass and mass density give a detailed understanding of dark matter properties within the galaxies.
