This data set consists of electric and magnetic field plots on microfilm provided by the University of Minnesota. Each time interval is plotted three times, first as the high frequency part of the electric field, second as the entire electric field spectrum, and third as the entire magnetic field spectrum. In the first plot (high frequency), two frequency channels are plotted in each graph. In the entire spectrum plots, five frequencies are plotted in each graph. No time smoothing is done in cruise mode, but three successive time samples are averaged together in fine frequency (ff) mode to give a time resolution on the plot of 30 s. Time at the bottom is given in UT hours and minutes. The antenna designations are as follows: b means the integrated output of the magnetic loop; wb means the unintegrated output of the magnetic loop; se means the short electric dipole (50 cm tip to tip); and long electric means the appropriate one of three long dipoles. In the lower lefthand corner of each plot are a series of tick marks at 20 dB intervals. These indicate signal strength above a threshold of approximately 10 microvolts at the receiver input of the E receivers, 2 microvolts at the input of the B receivers in the nonintegrating mode, and 2 microvolts for the receiver input in the integrating mode.
