Figure 4.
The graph shows canister pressure in kilo pascals over elapsed time from 5265 to 5285 days. Pressure rises sharply from near 0 to about 5000 kilo pascals around 5267 days, then gradually decreases to about 3500 kilo pascals by 5277 days. Around 5279 days, pressure increases again from about 2000 to nearly 5000 kilo pascals and stabilises close to 5000 kilo pascals towards 5285 days. Vertical dashed lines mark events labelled 1, 1 a, 1 b, 1 c, 2, 2 a, 2 b, and 2 c.Pressure of the canister during the initial pressurisation, showing the leak in pressure and the re-establishment of canister pressure
