These microfilm data, generated at NSSDC/SSC, are high time resolution (approximately 20 s) minimum-B channel wave amplitudes. Listed are a measurement designator, year, day of year, time of day (hour, minutes, seconds), and minimum-B amplitude. There are two columns per frame, and each column line consists of a pair of measurements. The measurement sequence on IMP has one minimum-B measurement at the start of a measurement sequence and one after the completion of the 14 narrow frequency channel measurements. The time presented in the listings is the time of the second B measurement. When the measurement listed is from the first B measurement, the measurement designator is in lower case letters. If a measurement is questionable, it is flagged by an * following the amplitude value. Because of the fact that when the antenna was in the shadow of the spacecraft the interference with solar cell-related noise was minimized, each measurement is in fact the minimum amplitude obtained during a sampling sequence that encompassed about one spacecraft resolution. Thus, the time given is accurate within approximately a second.
