      Updating an important SKA Low calibration requirement will ensure that the system is measured against parameters which are correct and therefore system performance is better understood.

    Description

      SKA1-SYS_REQ-3040 "SKA1 Low beam steering" reads:

      SKA1_Low, when forming station beams, shall steer them independently in both azimuth and elevation to an accuracy of better than 1/1000 of the half power beam width.

       

      https://jira.skatelescope.org/browse/SLSRO-166 says that this requirement is not feasible nor verifiable, and needs to be re-visited in the context of DDE calibration.
