The stations.dat file contains a list of all of the ground stations that will be assumed available for calculation of the ground tracks. The format of this file is exactly the same as the VLBI stations file. The locations of the ground VLBI stations in stations.dat are displayed as magenta circles on the world map. This file also has an END statement which functions as described above.
