| 6 | 3.38 ± 0.16 | 1.51 ± 0.28 | 0.23 ± 0.07 | 0.72 ± 0.04 |
Notes. The first column gives the hypothetical radius of the cluster. The second column is the 3D central mass density. The third and forth columns are the fitting parameters γ and a in Eq. (1). Finally, the last column is the ratio of observed mass that is limited by r< 1.4 pc to the total mass estimated of the cluster within a given radius.
