| The fringe offsets on any given night will depend on the POP configuration and the daily alignment. The table below gives a range of values where the fringes have been found for each cart on multiple nights across different POP configurations. The ranges should at least provide a guide for how far one might need to look to find fringes. The relative offsets between any pair of telescopes can be calculated from the differences between the ranges. | The fringe offsets on any given night will depend on the POP configuration and the daily alignment.
