Table 2.
Physical parameters derived by accretion disk modeling with SS73, KERRBB, and SLIMBH.
| a | Log M/M⊙ | η | λ | |
|---|---|---|---|---|
| SS73 | 0 | 8.6 | 0.083 | 0.0183 |
| KERRBB | −1 | 8.20 | 0.038 | 0.0605 |
| 0.627 | 8.52 | 0.094 | 0.0342 | |
| 0.9982 | 8.76 | 0.329 | 0.0340 | |
| SLIMBH | −1 | 8.18 | 0.038 | 0.0624 |
| 0.5856 | 8.52 | 0.0897 | 0.0360 | |
| 0.9982 | 8.83 | 0.329 | 0.0422 | |
Notes. Both KERRBB and SLIMBH provide a range of parameters instead of specific best values. We therefore include the maximally corotating (a = 0.998) and maximally counter-rotating (a = −1.0) solutions here along with the solutions corresponding to the independent virial-based mass measure by Shen et al. (2011, i.e., Mvir = 8.52 ± 0.39).
