The magnetic conjugation numerical file description
Magnetosphere models |
Region designations |
Corrected geomagnetic coordinates
|
Let us consider as an example
two numerical files with names tp.cng
This files contain the information about INTERBALL
Tail Probe and POLAR magnetic conjugations.
The Tsyganenko 87 (KP = 2) + IGRF magnetic field model are
used during magnetic mapping.
Stop trace altitude (km) 110.
The predicted magnetic conjugations correspond to the less then 5 deg
geocentric angular distance between the footprints.
For the selected time intervals the geographical
coordinates of the Tail Probe and POLAR magnetic mapping
are shown with 10 min. step.
For each time two lines (the first for Auroral Probe, the
second one for the POLAR) contain the coordinates as follows:
UTYYMMDD HHMMSS - Universal time (on the first line),
AnD - the footprints angular distance (on the first line),
dlt - the difference between two satellites corrected geomagnetic local times (on the second line),
dla - the difference between two satellite corrected geomagnetic latitude (on the second line),
Sat.1 - The name of the first satellite
Sat.2 - The name of the first satellite
R (RE) - the satellite geocentric distance,
GLAT (deg) - the satellite geographical latitude,
GLON (deg) - the satellite geographical longitude,
FNGLAT (deg) - the geographical latitude of the footprint,
FNGLON (deg) - the geographical longitude of the footprint,
REG - the simulative geophysical region in the satellite position
CMLT (h) - the corrected geomagnetic local time,
CORLAT (deg) - the invariant (corrected) geomagnetic latitude,
ARCln (Re) - the length of the magnetic field line (between satellite and footprint)
MOD IOPT - the used magnetic field model
