Web model / Tsyganenko 05: Vertical cut-off rigidity calculator



Year, from 1. jan. 1995 till 31. december 2015, for years before 1995
use model with Tsyganenko 96 external geomagnetic field
DOY = Day Of Year
Hour, from 0 till 23
Longitude, from 0 till 360 deg.
Latitude, from -88 till 88 deg.
Radius in units of Earth radii Re, from 1.00 to 10.00 Re
1.00 Re = 6371.2 km / 1.00 Re is Earth ground

- calculation can take one-two minutes
- calculation can run significantly longer time for Re > 1.1
- step in energy/rigidity resolution 0.1 GV
