The coordinate time series of radio sources are computed with two specific analysis configurations. The most common one (2023r) is the independent mode, updated as new observations arrive at the data center. The second configuration (global mode, 2023s) is made up of four global solutions, treating one fourth of the sources as arc parameters. The latter series are more accurate but are updated only once a year or so. Below is the list of sources available. The source name color indicates the length of the observational history (darker means longer). The ICRF3 defining sources are highlighted in yellow. Plots are available for sources observed in more than 100 sessions. The full sets of time series are available in a single file in SOLVE lso format:
