-When the co-ordinates for a map or plan are given in terms of a centre point rather than outside limits, the longitude and latitude ​that form the central axes are each recorded twice, ​in subfields $d and $e (longitude) and subfields ​$f and $g (latitude).+The co-ordinates for a place are given as a centre point. Howeverin compliance with the Unimarc Authorities format, a distinction between the westernmost and easternmost ​longitude and northernmost and southernmost ​latitude ​is made when a record is rendered in the CT Internal Format. For editing it is sufficient to fill in subfields $d (longitude) and $f (latitude). Once a record is saved, subfields $e and $g, repeating the values given in $d and $f are added automatically.

 +The order of subfields within this field doesn'​t matter. It might be most convenient to enter coordinates this way: \\ ''​123 ##​$fn0513202$de0095608''​.
