      Abstract
      The LOFAR observations of NGC 891 were done in interleaved mode, switching between scans on the calibrator 3C48 (at RA(J2000)=01:34:41.3, Dec(J2000)=+33:09:35and the target NGC 891. A total of 44 stations were used for this observation, of which 32 were core stations and 12 were remote stations. <P />The AMI (Arcminute Microkelvin Imager) consists of two radio arrays, the Small Array (SA) and the Large Array (LA), located at the Mullard Radio Astronomy Observatory (Cambridge, UK). <P />The SA data were taken as a single pointing with interleaved observations of the phase calibrator J0222+4302 and 3C286 used as a flux density and bandpass calibrator. The LA data were taken as a mosaic, consisting of seven pointings arranged on a hexagonal raster centred on NGC 891. Individual pointings were cycled between the pointing centers every 60s, switching to the phase calibrator J0222+4302 every 10min for 2min. <P />(2 data files).
