AMI Galactic Plane Survey at 16 GHz: II -- Full data release with
  extended coverage and improved processing
  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 $76^{\circ}
\lessapprox \ell \lessapprox 170^{\circ}$ between latitudes of $|b| \lessapprox
5^{\circ}$; here we present a second data release, extending the coverage to
$53^{\circ} \lessapprox \ell \lessapprox 193^{\circ}$ 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.
