Detection examples, discussed in Sect. 4.2, with low and high positional uncertainty (left and right respectively) for the MUST array (top), the LOFAR array (middle) and MeerKAT array (bottom). (Green squares) values of s₁/ s₂ and (a₂ − a₁) from each TAB. The red diamonds regions where s₁/ s₂ and (a₂ − a₁) from all TABs overlap. The blue circles the true position of a source. Red regions in all cases include the true location of the source and so is obscured in the left panels in particular.
