different features in the plot.
The plot shown is a dynamic spectrum from the URAP Radio Astronomy Receiver (RAR) for one day of data. The date of this data is shown at the top in a year,month,day format (i.e. 910203 corresponds to February 3, 1991). Frequency is plotted along the vertical axis and time along the horizontal axis. The frequency scale ranges from about 1 to 1000 kHz, and time (UT) is shown in hours of the day. Electric field wave intensity is shown in color, with more intense features shown in more prominent colors. Individual features may be clicked on to obtain further information about the physical phenomena causing them.
