In the 0.85 mm continuum band, the observations revealed two compact sources (with a separation of 2$\"$), one of them associated with IRAS 16547$-$4247, and the other one to the west. Both sources are well resolved angularly, revealing a clumpy structure. On the other hand, the line observations revealed a rich variety of molecular species related to both continuum sources.
