(1996A&AS..116..167M) for the contribution of the instrumental polarization to the closure phase. Instead, its often assumed that the displayed value is free of random errors, so the article describes a range of values where the true value probably lies. The maximum permissible error in an observation is 3.29s (where s is the standard deviation of sample distribution) and is used to separate mistakes or blunders from the random errors.
