 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.

-A new baseline solution was created on 2025Aug10 and has been set as the default on UT 2025Jun12. The solution is based on observations from UT 2025Feb21 through 2025Aug10. It was created using the IDL routine compute_baseline_solution.pro and weighting.
