Baseline length repeatabilities for CONT14. Shown are baseline length repeatabilities for CONT14, based on a KF solution with station-dependent ZWD noise parameters (blue) and on one with the same PSD for all stations (green), as a function of baseline length. Additionally, a reference solution from LSM is plotted (red). Every triple of blue, green, and red dots represents a single baseline. The curves are quadratic fits based on all available baselines
