This is not a temperature effect, but a high particle flux effect. This is due to the front detector being exposed to high intensity, low energy particles, whereas the detectors further down in the stack are better shielded. Leakage currents for detector A exceed yellow high and red high limits, for B only yellow high limits inside the radiation belts. As this recurs regularly, the respective warnings should be neglected. Except for a modest increase of the A leakage current during the first 10 days after turn-on, no persisting degradation due to the high flux environment is observed.
Currents drawn on the power rails are stable except for radiation belt passages.
There is ample margin to yellow and red limits.
