Open clusters in the UCC grouped according to various criteria to facilitate easy exploration.
UTI classification
This table shows the OCs in the UCC grouped by their UTI value.

C3 classification
This table shows the OCs in the UCC grouped by their C3 class.
| C3 | N | C3 | N | C3 | N | C3 | N |
|---|---|---|---|---|---|---|---|

Number of members
This table groups the OCs in the UCC in ranges of their estimated number of members
parameter N_50. This number is obtained identifying as members those stars with
P>50%, where P is the membership probability assigned by the fastMP method.
| N_50 | N | N_50 | N |
|---|---|---|---|
| == 0 | 14 | (0, 25] | 8750 |
| (25, 50] | 3971 | (50, 75] | 1484 |
| (75, 100] | 690 | (100, 250] | 1198 |
| (250, 500] | 415 | (500, 1000] | 153 |
| (1000, 2000] | 58 | > 2000 | 15 |
Probable duplicates
This table groups the OCs in the UCC by their estimated probability members. The percentage of shared members goes from <1% to 100% in some cases, which points to obvious duplicates.
| C_dup | N | C_dup | N |
|---|---|---|---|
| == 0.0 | 871 | (0.0, 0.1] | 571 |
| (0.1, 0.2] | 425 | (0.2, 0.3] | 276 |
