| Description: The clem_jpeg_version attribute specifies the specific set of parameters fed to the Matra compression chip that performed the onboard JPEG-variant discrete cosine transformation image compression. Two settings are documented as commonly used in the primary mission: "CLEM-JPEG-0" and, most often, "CLEM-JPEG-1." "CLEM-JPEG-2" and "CLEM-JPEG-3" also appear in some files but are not described in documentation. |

| Permissible Value(s) | Value | Value Meaning |
| | CLEM-JPEG-0 | CLEM-JPEG-0 denotes Matra's built-in quantization settings, weighted towards lower-frequency image data. |
| | CLEM-JPEG-1 | CLEM-JPEG-1 denotes settings that utilized a flat quantization table. |
| | CLEM-JPEG-2 | CLEM-JPEG-2 denotes some other group of settings not detailed in documentation. |
| | CLEM-JPEG-3 | CLEM-JPEG-3 denotes some other group of settings not detailed in documentation. |
| | None | A value of None indicates that Clementine did not compress this particular image. |
