The initial error interval and the final error interval under various reference phase differences.

	Initial Error Interval	Final Error Interval
$\Delta D_{23-12}$	$0~\frac{4{\delta }_{\phi \max }}{{\varphi }_{23,0}-{\varphi }_{12,0}}$	$\frac{\pi -4{\delta }_{\phi \max }}{{\varphi }_{23,0}-{\varphi }_{12,0}}~\frac{\pi }{{\varphi }_{23,0}-{\varphi }_{12,0}}$
$\Delta D_{12}$	$0~\frac{2\sqrt{2}{\delta }_{\phi \max }}{{\varphi }_{12,0}}$	$\frac{\pi -2\sqrt{2}{\delta }_{\phi \max }}{{\varphi }_{12,0}}~\frac{\pi }{{\varphi }_{12,0}}$
$\Delta D_{13}$	$0~\frac{2\sqrt{2}{\delta }_{\phi \max }}{{\varphi }_{13,0}}$	$\frac{\pi -2\sqrt{2}{\delta }_{\phi \max }}{{\varphi }_{13,0}}~\frac{\pi }{{\varphi }_{13,0}}$
