The bandpass of the magnetometer was 0 to 5 Hz, with a 20-dB per decade decrease for higher frequencies. The detector functioned well between launch and 10 October 1968, when the DC power converter failed. No useful data were obtained after that date.
The magnetometer's frequency range was limited to 0 to 5 Hz, with a gradual decrease in sensitivity for higher frequencies. The detector functioned until October 10th, 1968, when the DC power converter failed, leading to the loss of data collection.
