The spacecraft constellation ASCII file description

For the selected intervals of the UT the co-ordinates of 4 spacecraft are shown with 10-min step. For each time 4 lines (concerning to the 4 spacecraft) contain the co-ordinates as follows:

UTYYMMDD HHMMSS  - Date: YYYYMMDD and UT

R (Earth's radii) - the spacecraft geocentric distance,

REG              - the geomagnetic region in the spacecraft position,  

GMLAT (deg)      - the spacecraft geomagnetic latitude, 

GMLT (h)         - the spacecraft geomagnetic local time, 

CORLAT (deg)     - the corrected geomagnetic latitude,

CORMLT (h)       - the corrected geomagnetic local time

Xgsm (km)        - SC position  

Ygsm (km)        - in the 

Zgsm (km)        - GSM C/S 

In case any of the mentioned parameters is not determined, 99.99 replace its value.
