Forest Fire Clustering: A Novel Tool for Identifying Star Members of Clusters

In Tables 4 and 5, the Cluster column represents the name of the cluster. 

Table 4: The columns ra, dec, pmra, pmdec, and parallax correspond to the median values for the cluster's position, parallax, and proper motions, respectively. The [Fe/H] and [Fe/H]_err columns indicate the cluster's [Fe/H] and its associated error. The logt and log_t_err columns represent the logarithmic age and its error, while the m-M and m-M_err columns denote the distance modulus and its error. Additionally, the E(BP-RP) and E(BP-RP)_err columns specify the cluster's reddening and its error, and the A_V and A_V_err columns represent the extinction and its error.

Table 5: The rc_pc and e_rc_pc columns indicate the core radius and its error, while the rt_pc and e_rt_pc columns represent the tidal radius and its error. The rh_pc column provides the radius containing half of the total number of stars in the cluster, and the rhm_pc column gives the half-mass radius. The R_J and R_J_err columns represent the Jacobi radius and its error. The mass and mass_err columns show the total mass of the cluster and its error, and the fb column denotes the binary fraction of the cluster. Finally, the trlx and trlx_err columns represent the relaxation time and its error. The units of trlx and trlx_err are Myr

Note: NULL values for rc_pc, e_rc_pc, rt_pc, and e_rt_pc indicate the inapplicability of the RDP method. For Bootes I, NGC 104, NGC 3201, NGC 6121, NGC 6544, and NGC 6656, the parameters listed as “N/A”—including rhm, rJ, rJ_err, mass, mass_err, fb, trlx_Myr, and trlx_err—cannot be determined using our methods due to their faint magnitudes. This limitation arises because Gaia’s observational capacity extends only to 21 mag.
