Let us consider as an example the file with the name:
t4d17.txt.
This file contains the information about IB_1 (Tail Probe) magnetic
conjugations with another 3 SC as a function of the universal
time.
The less then 5 degree value of the relative geocentric angular
distance between the footprints of the SC is used as a
criterion of the magnetic conjugation.
The footprins coordinates are calculated by the SC mapping via magnetic field
lines trassing.
On the last column of the file is shown the magnetic field
model version (MOD
IOPT) used during magnetic mapping.
For selected time intervals the information as follows is shown
with 10-min step (in two or more lines for each moment):
