::'''$e - Coordinates - easternmost longitude'''

::'''$f - Coordinates - northernmost latitude'''

::'''$g - Coordinates - southernmost latitude'''

:::Subfields $d, $e, $f, and $g individually identify the four coordinates of the geographic entity. Subfield $d represents the westernmost extent of the item; subfield $e, the easternmost extent; subfield $f, the northernmost extent; and subfield $g, the southernmost extent. The abbreviations for the hemispheres are: ''N = North, S = South, E = East, W = West''.

:::Subfields $d, $e, $f, and $g always appear together. The coordinates may be recorded in the form hdddmmss (hemisphere-degrees-minutes-seconds), however, other forms are also allowed, such as decimal degrees. The subelements are each right justified and unused positions contain zeros.

:::The subelements are each right justified and unused positions contain zeros.

:::If the coordinates for a geographic entity are given in terms of a center point rather than outside limits, the longitude and latitude which form the central axis are recorded twice (in subfields $d and $e and in $f and $g, respectively).

::'''$j - Declination - northern limit'''

::'''$k - Declination - southern limit'''

:::Subfields $j and $k are each eight characters in length and record the declination in the form ''hdddmmss'' (hemisphere-degrees-minutes-seconds). The degree, minute and second elements are each right justified and the unused positions contain zeros. (If declination of center is known, it is repeated in both subfields).

::'''$m - Right ascension - eastern limit'''

::'''$n - Right ascension - western limit'''
:::Subfields $j, $k, $m, and $n are used with celestial entities and contain the limits of the declination and the right ascension.

:::Subfields $j and $k are each eight characters in length and record the declination in the form ''hdddmmss'' (hemisphere-degrees-minutes-seconds). The degree, minute and second elements are each right justified and the unused positions contain zeros. (If declination of center is known, it is repeated in both subfields).

:::Subfield $m and $n are each six characters in length and record the right ascension in the form ''hhmmss'' (hour-minute-seconds). The hour, minute and second elements are each right justified and the unused positions contain zeros. (If the right ascension of center is known, it is repeated in both subfields).
