A colour composite image of IRAC photometric bands where red is IRAC 8.0 μm, green is 4.5 μm and blue is 3.6 μm. Images are logarithmically scaled and combined into one composite image. The area enclosed in a white rectangle is the target source JCMT I18354−0649S and the image on the right is a close-up of this region. GPSR5 25.398−0.141 and W42 are nearby UCHii regions. In both images, contours are from 850 μm continuum JCMT SCUBA data. The contours start at 3σ and increase by 1σ thereafter. The position of each object and the scale are indicated on the image.
