Program ners_eop retrieves the Earth orientation parameters at the
specified epoch from the Network Earth Rotation Service (NERS)
server and prints it in stdout.
Usage:
ners_eop [-h] [-c config_file] [-p param] [-t date] [-v verb_level] [-r] [-i]
-h prints this file and exits.
-c config_file name of the ners client configuration file.
If omitted, ners_eop will first search $HOME/.ners_config
and if it does not find, uses file share/ners.config
in ners installation directory.
-p param EOP parameter(s) to be displayed. Supported parameters:
