Sectored X-ray Plots on Microfilm


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1974-12-17 to 1984-02-12


This data set consists of sectored X-ray plots on microfilm submitted by the experimenter. The sectored X-ray plot contains counts per second on an every-readout basis. Each frame covers a 5-h timespan, and each point is an average of one set of eight sectors. On the bottom of the plot is a ranking table, with the three most intense directions indicated such that the most intense sector is placed on top. The time on the plot consists of the spacecraft event time associated with the readout of the first sector. The second time is a correction for one-way light time to the sun and represents the event time at the sun. The spacecraft position in ecliptic coordinates is given at the top of each frame. The name of the spacecraft is also given at the top of the frame.
