The Cambridge Low Frequency Synthesis Telescope (CLFST) has baselines which are offset from the E-W direction by about 3°. The wide-field mapping problem has been overcome by the use of beam-sets, or artificial maps consisting of grids of synthesized beams, which incorporate the effects of both the geometric and chromatic aberration. By appropriate interpolation we can find a good approximation to the beam-shape at any point on a map.
