-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 twicein subfields $d and $e (longitudeand subfields $f and $g (latitude). //However, the current editing system will automatically add the repeated subfield where it's missing (i.e. it is sufficient to fill in subfields $d and $f when entering coordinates, subfields $e and $g will be addedwhen the record is saved.)//+The co-ordinates for a place are given as a centre point. Howeverin compliance with the Unimarc Authorities formata 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''.
