These are used to investigate trends in the colours, magnitudes and structures of the sources, together with spatial variations in flux ratio. It is concluded that most of the sources are remarkably similar, and have comparable variations in flux ratio as a function of position within the shells, together with very narrowly defined ranges of colour index. Description: We have surveyed the entire GLIMPSE Atlas for likely compact HII regions (see Benjamin et al., 2003PASP..115..953B for the seminal article on this Atlas). Specifically, the GLIMPSE team has provided individual, and slightly overlapping images of the ATLAS for each IRAC band, and for ranges of Δl=1.1° in galactic longitude, and Δb=0.8° in galactic latitude, leading to a total of 1344 plates for the four bands combined [the high resolution (0.6arcsec/pix) data version is available at 1.1x0.8_mosaics/.
