M_{1.6 kpc}(t=0)	1.30 × 10⁷		8.93 × 10⁸
ΔM_{1.6 kpc}	0.02 × 10⁷	(1.5%)	4.29 × 10⁸	(48%)
M_{3.0 kpc}(t=0)	1.31 × 10⁷		3.30 × 10⁹
ΔM_{3.0 kpc}	0.001 × 10⁷	(<1%)	4.16 ×10⁹	(46%)

Notes. Initial mass within 1.6 kpc (M₁_{.6 kpc}) and 3 kpc (M_{3 kpc}), and corresponding mass loss ΔM ≡ M(t = 12 Gyr) − M(t = 0) for the stellar (second column) and DM (fourth column) components. The third and fifth columns indicate the corresponding per cent mass loss.
