Abstract
We present observations and analysis of a sample of 123 galaxy clusters from
the 2013 Planck catalogue of Sunyaev-Zel'dovich sources with the Arcminute
Microkelvin Imager (AMI), a ground-based radio interferometer. AMI provides an
independent measurement with higher angular resolution, 3 arcmin compared to
the Planck beams of 5-10 arcmin. The AMI observations thus provide validation
of the cluster detections, improved positional estimates, and a consistency
check on the fitted 'size' (
