 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.
-A new baseline solution was created on 2024Jun27 and has been set as the default. The solution is based on mircx/mystic observations from UT 2023Jun28 through 2024Jun27. It was created using Aaron's python baseline solution code (beams fixed; XYZ, light, and pops optimized). We used an extended date range to improve [[:chara:files:figure_optimal_test_2024jun27.png|sky coverage]] and cover more pop configurations.
+A new baseline solution was created on 2024Jul08 and has been set as the default on UT 2024Jul11. The solution is based on mircx/mystic observations from UT 2024Apr04 through 2024Jul02. It was created using Aaron's python baseline solution code (beams fixed; XYZ, light, and pops optimized). We used a limited date range in attempt to keep the offsets closer to zero.
