Coordinate fluctuation of three baselines as labeled in each day of year (DOY). Left (a, d, and g), center (b, e, and h), and right (c, f, and i) columns indicate north, east, and up components, respectively. Neither low-pass filtering (LPF) nor sidereal filtering (SRF) is applied. Green color indicates epochs filled by interpolation of neighboring epochs during the data cleaning process
