| Description: The radial "zone" or "shell" of the target for which the observations were collected or which are represented in the product(s). The value may depend on wavelength_range and size of the target. |

| Permissible Value(s) | Value | Value Meaning |
| | Atmosphere | an envelope of uncharged gases and particles surrounding the target and bound to it primarily by gravitational forces |
| | Dynamics | The data provide information relating to the orbital motion of one or more bodies (e.g., astrometric observations). |
| | Heliosheath | the portion of the solar atmosphere between the termination shock and heliopause, which is dominated by shocked, subsonic solar wind |
| | Heliosphere | the solar atmosphere extending roughly from the outer corona to the edge of the solar plasma at the heliopause, which separates primarily solar plasma from the interstellar medium. |
| | Interior | the solid and/or liquid portion of a target enclosed by its surface. |
| | Interstellar | the region between stars, which is outside of any star's heliopause. |
| | Ionosphere | an envelope of plasma and charged particles surrounding the target and bound to it primarily by gravitational forces. |
| | Magnetosphere | an envelope of charged particles, bounded on the upper side by the magnetopause and which is primarily under the control of the target body's magnetic field. |
| | Rings | A ring is a narrow band or disc orbiting an astronomical body (planet, dwarf planet, satellite, asteroid, etc.) that is composed of solid material ranging in size from fine dust to a few tens of kilometers. |
| | Surface | the boundary between the solid/liquid portion of a target and its atmosphere, ionosphere, or magnetosphere (or space). |
