Maps of the coherent Superterp beam, also known as a tied-array beam. These were made by simultaneously recording 217 coherent and 1 incoherent beam for all 12 Superterp HBA sub-stations from 120–168 MHz. The bright pulsar B0329+54 was observed twice for 5 min, near zenith and the color maps reflect the S/N of the dedispersed and folded signal in various directions. The background color reflects the S/N of the simultaneously acquired incoherent beam. Left: observation L57554 in which the tied-array beams were arranged in a hexogonal grid with spacing 0.05°. This densely samples the main lobe of the Superterp beam. Right: observation L57553 in which the tied-array beams were more widely spaced (0.15° apart) in order to probe the sidelobes. Asymmetry in the sidelobe pattern is due to imperfect phasing of the coherent beam.
