    • In each test of the onset of noisy operation, the power consumption increased drastically and the spacecraft flight software generated multiple error event reports (EVRs). A software patch was implemented to turn the DFMI off if it went into a noisy state. The noise started in all counters at the same time, and in the most sensitive case (m1 counter) it saturated the counter in a few seconds. Nothing similar was observed during the Wild 2 encounter: We have not seen any noise, no EVRs were generated, and the instrument was not turned off by the software patch. In addition, the calibration performed immediately after the encounter showed nominal expected performance, and the instrument was turned off before it went noisy, some 2000 s after it was turned on.
