Introduction
------------
The `delay_meas` module provides utilities to report the time took by every packet to traverse the CMX.

The `Polars <https://pola.rs>`_ library is used for efficient data manipulation and analysis.

This consist in two steps:

- Retrieving the central_service.log file containing the delay measurement results. This file is found on the CMX in the DATAUNIT/rohde-schwarz/log/DAU directory.
- Use a function in the 'delay_meas' utilities to get Polars Dataframes.
