  1. From top to bottom, the given parameters are the latitude and longitude of the selected locations, the angle between the geomagnetic field and the downward vertical, the critical frequency of the ionospheric F2 layer, the wave frequency, electron cyclotron frequency in the geomagnetic field, the effective collision frequency, the scale height, the reflection height of O-mode wave, and the upper-hybrid resonance altitude
