Parameter summary for the idealised tests.

Idealised Milky Way galaxy

	θ_z,o (º)	M_BH,0 (M_⊙)	ƒ_Edd
IdealGal-fld	170	5× 10⁶	1
IdealGal-120	120	5× 10⁶	1
IdealGal-30	30	5× 10⁶	1
IdealGal-5e5	170	5× 10⁵	1
IdealGal-5e7	170	5× 10⁷	1
IdealGal-0.3	170	5× 10⁶	0.3

Notes. M_BH,0 is the BH mass in the ICs, θ_Z,0 is the angle subtended by the initial BH spin direction and the positive z axis, ƒ_Edd = Ṁ_BH/Ṁ_Edd is the Eddington ratio.
