Programs ners_eopser generates the Earth orientation parameters time series
for the specified range of epochs with the specified step using the Network
Earth Rotation Service server and prints it in stdout.
Usage:
ners_eopser [-h] [-c config_file] -p param_name -b start date -e stop date
-s time_step [-v verbosity] [-r ]
-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_name EOP parameter(s) to be displayed. Supported parameters:
euler three parameters:
Euler angle with respect to axis 1 (rad)
Euler angle with respect to axis 2 (rad)
