Ann: Mukuyu-2 fluid sampling progress update, page-633

Some clues;

The x-axis is time from the start of cleanup ... time scale unkown

Each of the tracks or plots are different sensors in the MDT along the same time scale. As can be seen there are >10 readings. If one sensor fails it can impact the analysis.
