Polarizations A and B are arranged vertically in separate images.
The frequency range is about 100 (bottom) to 300 MHz (top of each panel).
Dropouts occur if the 45-foot antenna loses tracking.
Vertical ticks every 10 minutes, horizontal ticks at 40 MHz intervals.
Vertical white lines (dotted lines on light curve) indicate local sunrise and sunset (to within 2 minutes).
