Notes. Entries are: number (first column), name (2nd), position (3rd), radius (4th), H2 particle density (5th), density uncertainty factor (6th) and mass (7th), references (8th). The parameters of the magnetic field strength B and δB the uncertainty factor of themagnetic field are based on the results of this work (see a detailed description in Sect. 3). Further, Rs is the Schwarzschild radius of SgrA* ≃ 1.12 × 1012 cm.
