Parameters of the Sparkler-like exponential disc (first row) and of the three MN disks (second, third, and fourth rows) that, summed together, better approximate the potential of the original exponential disc (see Smith et al. 2015).
| Disc | Md | Scale radius | Scale height |
|---|---|---|---|
| [109 M⊙] | [kpc] | [kpc] | |
| exp | 8.79 | 2.77 | 0.25 |
| MN1 | 1.37 | 1.57 | 0.3 |
| MN2 | −48.82 | 7.16 | 0.3 |
| MN2 | 56.87 | 6.23 | 0.3 |
Notes. The first column is the ID of the disc (exp for the exponential disc; MN1, MN2 and MN3 for the three MN disks), the second column is the total mass of the disc Md, the third column is the disc scale radius (Rd for the exponential disc and a for the MN disks) and the fourth column is the disc scale height (hz for the exponential disc and b for the MN disks).
