Let consider as an example the file with name 'ta.cng'. This file contains the information about IB_TAIL and IB_AUR (AURORAL) magnetic conjugations as a function of the real time, shown as UT or Moscow time (MT = UT + 3h).
The predicted magnetic conjugations correspond to the less then 5 deg relative geocentric angular distance of the two satellites magnetic footprints.
The magnetic field model version (MOD IOPT) used during magnetic mapping is shown on the last column of the file.
For selected time intervals with 10-min step for both satellites the information as follows is shown (two lines for each time):
|
1. |
UTYYMMDD |
DATE: year (YYYY), month (MM), day (DD) |
|
1.1 |
dcormlt = dlt (h) |
the difference between two satellites corrected geomagnetic local times (see as well column 11) |
|
2. |
HHMMSS |
.hhmnss: Hours (hh), min (mn), sec (ss) |
|
2.1 |
dcorlat = dla (deg) |

|
6. |
GLAT (deg) |
the satellite geographical latitude |
|
7. |
GLON (deg) |
