Notes.

(a)

Core 22 is associated with cores 5 and 8. Core 25 is associated with core 19. Core 26 is associated with core 18. Core 27 is partially associated with core 35. Core 29 is associated with core 2. Core 32 is associated with core 7. Core 35 is partially associated with core 27.

(b)

Geometric mean diameter of the core. U denotes that the core is unresolved.

(c)

Y denotes that the core is associated with 25 GHz emission above 0.125 mJy beam-1 in a 2.2′′× 1.9′′ beam (Mills et al., in prep.).
