Notes. Column description: (1) case identifier; (2) density ratio η; (3) Mach number M; (4) exponent α characterizing the initial density distribution; (5) ratio between jet and external pressure; (6) jet velocity; (7) jet kinetic power; (8) domain extension in the three directions; (9) number of grid points in the three directions; (10) short description of the case; (11) resulting FR morphology. Jet velocity and kinetic power are computed with the reference values for the external medium parameters (see Sect. 3).
