reformat_track_load_table_log_msg_args(load_mode, sequence_length, timestamp_data, az_data, el_data, max_entries_to_log=10)

Truncate TrackLoadTable command args sequences.

This is done by removing the padded zeroes in the supplied tracktable to be shown in the log message.

Parameters:

• load_mode (str) – The tracktable load mode value.

• sequence_length (int) – The number of valid data entries in the seqeunces.

• timestamp_data (list[float]) – List of tracktable timestamp values.

• az_data (list[float]) – List of tracktable azimuth values.

• el_data (list[float]) – List of tracktable elevation values.

Returns:

Formatted string with truncated arguments and zero padding count.

Return type:

str
