Continuum emission towards AFGL 2591 at 106.7 and 110.5 GHz (~2.8 and 2.7 mm respectively), shown in both contours and greyscale. The rms noise in the images is σ = 2.2 and 2.1 mJy beam^-1 respectively. The greyscales extend from −3    ×    σ to 65.5 and 54.0 mJy beam^-1. Contours are at −3,3,4,5,7,10,15   and   20    ×    σ. The crosses show the positions of VLA 1 to 3. The synthesised beams are 4.9′′    ×    4.1′′ PA = −4.8° and 4.3′′    ×    3.5′′ PA = 95° respectively.
