A two temperature greybody model reproduces the spectrum very well.

Warm dust
Contours: [OIII] line emission
Contours: Total CO(J=1-0)
The warm dust and the [OIII] line emission (88um) are well correlated with each other, which are associated with the Arches and the Quintuplet cluster.However, the cold dust is not associated with either the Arches or the Quintuplet cluster.
