Downloads and initialises the IERS file from the mirror or local links.

Returns:

None

Return type:

None

generate_program_track_table(task_callback: ska_tango_base.base.TaskCallbackType, task_abort_event=None) → Tuple[ska_control_model.TaskStatus, str]

Submit GenerateProgramTrackTable as a long-running background task.

Parameters:
