  • The Field of View (FoV) of the ATA array is set by the size of the 6m dishes and is 3.5 deg/(f in GHz) FWHM.
  • Below 7 GHz the FoV is larger than the full moon.  
  • The individual synthesized beams have a diameter ~= FoV *(6 m/300 m) where 300 m is approximately the size of the largest baseline in the ATA-42 array.
