Notes. Positional offsets in right ascension and declination are given in arcseconds, relative to the Wolf-Rayet member Q12 in the cluster core, RA 17:46:15.13, Dec −28:49:34.7. Sources identified as proper motion members have a membership index of 1, while sources without reliable membership information are labelled as −1. Non-members are likely field stars and are not shown here.

(a)

Source 20 in Field 2 is identical to source 8 in Field 1.

(b)

Source 27 in Field 5 is identical to source 19 in Field 1.
