| | Calibrated | Data converted to physical units, which makes values independent of the instrument. |
| | Derived | Results that have been distilled from one or more calibrated data products (for example, maps, gravity or magnetic fields, or ring particle size distributions). Supplementary data, such as calibration tables or tables of viewing geometry, used to interpret observational data should also be classified as "derived" data if not easily matched to one of the other categories. |
| | Partially Processed | Data that have been processed beyond the raw level but which have not yet reached calibrated status. |
| | Raw | Original data from an instrument. If compression, reformatting, packetization, or other translation has been applied to facilitate data transmission or storage, those processes will be reversed so that the archived data are in a PDS approved archive format. |
