AMI Galactic Plane Survey at 16 GHz: II -- Full data release with extended coverage and improved processing

Abstract

The Arcminute Microkelvin Imager Galactic Plane Survey (AMIGPS) provides mJy-sensitivity, arcminute-resolution interferometric images of the northern Galactic plane at $\approx$ 16 GHz. The first data release covered $76^{\circ }⪅\ell ⪅170^{\circ }$ between latitudes of $|b|⪅5^{\circ }$; here we present a second data release, extending the coverage to $53^{\circ }⪅\ell ⪅193^{\circ }$ and including high-latitude extensions to cover the Taurus and California giant molecular cloud regions, and the recently discovered large supernova remnant G159.6+7.3. The total coverage is now 1777 deg${}^2$ and the catalogue contains 6509 sources. We also describe the improvements to the data processing pipeline which improves the positional and flux density accuracies of the survey.
