NGC 6715 (M 54) At the centre of the main body
Terzan 7 In the main body (Pcol = 0)
Arp 2 In the main body (Pcol = 0)
Terzan 8 In the main body (Pcol = 0)
Pal 12 In the trailing arm (Pcol = 0)
Whiting 1 In the trailing arm (Pcol = 1)

Good/interesting candidate members

NGC 2419 Associated with a very distant
and old arm (Pcol = 8)
NGC 5634 Possibly associated with an old arm (Pcol = 3−8)
NGC 4147 Possibly associated with an old arm (Pcol = 3−8)

Unlikely candidate members

Pal 2 Compatible with an old arm (Pcol = 5−8)
but > 200 km s−1 difference in VGSR with LM10
NGC 6284 Compatible with an old arm (Pcol = 4−8)
but > 250 km s−1 difference in VGSR with LM10

Notes. The reported Pcol values indicate the Pcol range spanned by of the particles of the LM10 model in the surroundings of the cluster.
