| Permissible Value(s) | Value | Value Meaning |
| | 2D (Spectroscopy) | A 2D array in which each pixel value directly represents the spectral measurement at that point. The physical axes of the array align with the axes of the spectral data. |
| | Color (Imaging) | 3D data, typically with two spatial axes, where the third axis contains display color levels (RGB, CMYK, false color, etc.) |
| | Color Movie (Imaging) | 4D data, typically with two spatial, one color, and one temporal axis |
| | Dust Study (Small Bodies) | Dust measurements of all kinds and all targets |
| | Dynamical Properties (Small Bodies) | Orbital parameters, proper elements, etc. |
| | Electric (Fields) | Electrical field measurements |
| | Electrons (Particles) | Electron measurements |
| | Gas Study (Small Bodies) | Gas measurements of all kinds and targets |
| | Grayscale (Imaging) | 2D data, typically with two spatial axes |
| | Historical Reference (Small Bodies) | Discovery circumstances, reference collections |
| | Ions (Particles) | Ion measurements |
| | Lightcurve (Small Bodies) | Light intensity variation with time, including rotational, secular, and occultation light curves |
| | Linear (Spectroscopy) | A table representing a single spectrum |
| | Magnetic (Fields) | Magnetic field measurements |
| | Meteoritics (Small Bodies) | Meteoroid streams, meteorite studies |
| | Meteorology (Atmospheres) | Meteorological observations |
| | Movie (Imaging) | 3D data, typically with two spatial and one temporal axis |

| | Polarimetry (Flux Measurements) | Linear and circular polarization studies |
| | Production Rates (Small Bodies) | Quantification of mass loss from, e.g., the nucleus of a comet: molecular production rates, Af?, etc. |
| | Ring Compositional Map (Ring-Moon Systems) | 3D data, typically with two spatial axes, where the third axis uses either color or intensity to depict chemical or particle size variations within the rings. |
| | Ring Occultation Profile (Ring-Moon Systems) | Derived ring occultation data uniformly sampled along the radial axis. The occulted signal may be either, radio, solar, or stellar in origin. |
| | Ring Thermal Map (Ring-Moon Systems) | 3D data, typically with two spatial axes, where the third axis uses either color or intensity to depict temperature variations within the rings. |
| | Satellite Astrometry (Ring-Moon Systems) | Astrometry of natural satellite in ring systems |
| | Shape Model (Small Bodies) | Shape models, slope models, terrain models, elevation models, etc. |
| | Spectral Cube (Spectroscopy) | Any 3D structure containing spectral data |
| | Spectral Image (Spectroscopy) | A 2D image of a spectrum, as projected on a focal plane. There may be multiple orders present, and the axes of the spectrum/spectra typically do not align with the edges of the image. |
| | Structure (Atmospheres) | Atmospheric structure observations |
| | Tabulated (Spectroscopy) | A table with one spectrum per record, possibly for a different target in each record |
| | Taxonomy (Small Bodies) | Physical and dynamical taxonomies of small bodies |
