Location of the satellite's magnetic footprint trace inside of the polygon of some magnetic observatory is used as a criterion of its magnetic conjugation.
During magnetic conjugations selection the pre-calculated by magnetic mapping satellite's footprints geographical co-ordinates are used.
The name of the output file (with extension '.gbs') contains the satellite's short name (1 letter) and magnetic observatory short name (1 letter).
For example the numerical file with name 'ti.gbs' contains the magnetic conjugations of the IB_TAIL and SUPER-DARN radar's pair 1 (SASKATOON & KAPUSKASING) with the short name i (see the list of the used magnetic observatory and its co-ordinates).
See the output file description.
