The polar diagram shows the Spacecraft corrected geomagnetic co-ordinates: co-latitude - local time with 10-min step.
Each point is labelled by the symbol, corresponding to the simulative geophysical region in the Spacecraft position.
The geomagnetic co-latitude in the range (10°, 50°) is shown with 10° step.
The geomagnetic local time meridians correspond to 0, 6, 12 and 18 hours.
