325 GHz masers, summed over <17, 17–27, and >27 km s-1, shown in blue, green, and red. Contour levels start at 30 Jy; higher levels are at 24%, 48%, 72%, and 96% of the peak, where the peak is 2184, 1018, and 903 Jy for the red, green, and blue ranges. These levels have been chosen to emphasise the brighter emission and indicate the total extent at a uniform sensitivity limit (to 1–3% peak), omitting fine details. The cross marks VY.
