↵1 Distribution from all 16 proximal sites (2 sites/date, 8 dates)
↵2 Distribution from all 32 lateral sites (4 sites/date, 8 dates)
↵3 Distribution from those lateral sites beneath the shoulder (0.5 to 1.5 times branch diameter)
↵4 Distribution from those sites outside of the shoulder (>1.5 times the branch diameter)
