Arcminute Microkelvin Imager (AMI) Galactic Plane Survey (AMIGPS)

This 15.7 GHz survey has been carried out using the Arcminute Microkelvin Imager Small Array , which is operated by the Cavendish Astrophysics Group at Lord's Bridge, Cambridgeshire. It is a radio synthesis telescope comprising ten 3.7-m diameter dishes. The AMI Galactic Plane Survey is a large survey of the Galactic Plane, covering the area 76°<l<170° between latitudes of ıbı<5°. The angular resolution is approximately 3'. The units of the HEALPix maps are Jy/Beam.
