As illustrated in Figure M.4.4-1, for systems that either do not allow measurements at the pole (=180^o), e.g., using distributed-axes positioners, or systems that have the positioners/support structures block the radiation towards the pole (=180^o), e.g., combined-axes positioners, measurements beyond 150^o in  can be skipped and interpolated instead for measurement grids defined in Annex M.4.1.
