Description
Content
Time series of 1210 radio source positions at K-band from Very Long Baseline Array.
Number of radio sources with session-wise estimated coordinates:
- 1089 in vie_k_250819a
- 1097 in vie_k_250819b
Positions of defining ICRF3sx radio sources which are not included in the respective _sts.txt file (~120) were fixed in the adjustment. See Series information.
